The concentration of the electromagnetic field inside WG dielectric resonators [1] has been emphatized as a cause of sensitivity enhancement in the techniques of ESR spectroscopy [2]. This work is an experimental study dedicated to the detection of optical and infrared radiation utilizing as a thermal detector a small polycristalline sample of high-T_c superconducting material placed inside a WG resonator and using the techniques of microwave measurements [3]. The experimental set-up, as depicted in Fig 1, consisted essentially in a simple transmission-cavity spectrometer operated in the frequency range from 18 to 26.5 GHz (K-band). The resonator was a 20 mm alumina disk, 3 mm thick, excited in the WGH modes of resonance with dielectric rod waveguides, and supported by a liquid nitrogen cold finger in high vacuum conditions. The transmitted power was detected by a crystal receiver. A few tens of μg of YB₂C₃O_7-δ powder [4], was pressed at the bottom of a .9 mm hole, in a region of high electromagnetic field intensity. The hole was drilled in radial direction into the curved surface of the disk and was about 1.5 mm deep. A microwave sweep oscillator of 10 dBm of output power was fixed at the resonant frequency of the loaded resonator, the temperature being sligthly lower than the critical temperature of the superconducting material. The transmitted power level was recorded while a red-laser beam was directed inside the hole. The recorded signals, as reported in Fig 2, give indications about the response time, and the sensitivity attainable. The upper trace represents the transmitted signal variation obtained illuminating the resonator hole with a non focalized 1 mw CW red laser beam. The rise time of the signal was of τ=.5 s , and it was found to be proportional, within limits, to the sample mass. The voltage signal was proportional to the incident microwave power. The lower trace represents the transmission curves of the resonator as a function of time: with "laser on" (the first two peaks), and with "laser off" (the three peaks to the rigth) . These curves were obtained by sweeping repeatedly the microwave source +/−10 MHz around the frequency of 24.4 MHz, i.e. the resonant frequency of the WG disk resonator with laser "off'. The resonant frequency shift under "laser on" conditions was of 4 MHz and the relative Q-factor variation was of about 17%. Both the resonant frequency and the Q-factor diminished as the sample temperature raised over T_c. The observed signals are attributable to the phase transition of the superconducting sample under the heating effect of light. Chopped laser signals up to 10 Hz could be recorded in a straigth video- detection scheme, with a signal to noise ratio of 10. The loaded Q-factor was always of the order of 10³. The quasi black-body absorption characteristic of the powder charged hole, acting much as a light-trap, makes the device capable of detecting infrared radiations in a wide range of wavelengths. The maximum voltage "responsivity" (at 0 hertz) was of about 200 V/W , with a voltage noise less than of .1 mV/(Hz)^1/2. Experiments with higher Q-factor dielectric resonators and epitaxially deposited thin superconducting films for characterization purposes at microwave frequencies are in project.

An open structure SIS mixer for 350 GHz Paper

Today superconducting tunnel junctions are the best mixer elements in the 0.7 to 3 mm wavelength range. This open structure mixer, built on the basis of such a junction approaches the best waveguide systems (1). Its particular merrits are low cost, easy assembly, and convenient tuning by one single element. The mixer element is a series array of 3 PbBi junctions deposited on a fused-quartz substrate. The junctions are positioned in the middle of a planar dipole structure. In order to isolate the bias circuit and the IF amplifier band stop filters were deposited on both ends of the dipole. The usual perodic high-low impedance structure was used for these filters. A substrate holder presses the substrate with moderate force towards an elliptical immersion lens made from crystal quartz. This concept was pioneered by (2). Special features of our design are (i) the junction composition, providing a gap voltage of 10mV for the array, (ii) the use of a resonant dipole feed with choked bias connections, (iii) the imaging by one single aspheric lens of crystal quartz. The lens-junction assembly is mounted in a copper block which also carries the IF connector. A 3 mm screw in the substrate holder provides a movable backplane behind the dipole feed. On both sides of the mixer block superconducting coils with 6000 turns each provide the necessary magnetic field. The results below were measured at 100 mA corresponding to 110 Gauβ at the junction. At this flux density the Josephson effect is at its first minimum. Mixer, coils, and a low noise preamplifier are mounted in a ℓHe bath dewar which has a quiescent hold time of 50 hours. An uncoated 1.05 mm crystal quartz window on the 77 K radiation shield rejects 10 μm radiation and has its resonant transmission at 340 GHz. A 0.25 mm Mylar window, resonant at 350 GHz, seals the vacuum. The local oscillator, (4) is combined with the signal by a 35 μm Mylar foil transmitting nominally 96% of the signal and 4% of the ℒO power. Apart from the immersion lens in the mixer block there is no further lens in the signal path. The ℒO source is focused onto the mixer by a plastic lens between the beam combiner and the ℒO output. The receiver noise was measured for a number of frequencies (fig 1) using the Y-factor method where an absorber at 290 K and a wet absorber at 77 K stored in ℓN₂ were brought into the signal path. The best value of 214 K at 342 GHz, measured with a bath temperature of 1.5K, coincides with the resonance of the IR-filter. The pumped and unpumped i/v curve together with the calibration curves for hot and cold load are given in fig.2. Receiver noise as a function of IF frequency (fig 3) was measured in 50 MHz bandwidth and coincides with the noise curve of the preamplifier. The angular diagram (fig 4) was measured using a chopped cold load with a 2 degree aperture moved in 1 degree steps. It meets the design goal of a clean, symmetrical f/10 beam and would match the Cassegrain beam of e.g. the 30 m IRAM telescope on Pico Veleta without additional optics.

A modular 300 GHz waveguide mixer with ultra-broad IF-bandwidth Paper

The design and preliminary results of an experimental fundamental 300 GHz mixer are reported. The mixer has a modular construction consisting of three major parts (see Fig. 1). They are the waveguide connector with claw flange, the diode mount unit with IF-connector (see Fig. 2) and the backshort unit with micrometer drive. This separable building-up enables on the one hand a simple replacing of the diode mount in case of damage by another mount held on hand. And of course the procedure of contacting itself is facilitated by observing the whisker through the waveguide under a microscope. And on the other hand separated experimental studies of capabilities of the single units independent of another are made possible. So for example different types of backshorts can be tested. Furtheron one limitation of broadband mixer design, i.e. the coaxial mounting structure /2/, is experimentally investigated. Therefore a special IF-coupling is realized at the diode mount. The waveguide for 300 GHz has the dimensions 0.864 x 0.432 mm² and is not height reduced because of a practical fabrication limit of the whisker length of 0.35 mm. The honeycomb Schottky diode is glued on a turned bush fixed on the center conductor of the glass bead of a K-connector (see Fig. 3). So a one step lowpass filter, which provides a short circuit for 300 GHz, and a good mechanical stability are achieved. Furtheron the extremely short way for the IF provides a very small dependence of the IF-impedance versus frequency. The IF-impedance at a bias current of 1 mA shows (see Fig. 4) in the bandwidth 0.04 - 10 GHz a mismatch loss of less than 0.09 dB and even for the bandwidth 0.04 - 15 GHz less than 0.7 dB related to 50 Ohm. The IF-impedance is investigated with no LO-power applied. Nevertheless the results are transferable. For low level of LO-power (less than 1 mW) there is no significant deviation of IF-impedance. And even for high LO-power the IF-reflection coefficient shows a similar variation of phase versus frequency but at a higher amount of reflection. And the small dependence of phase variation is decisive for a broad-band power and noise matching. In connection with a backshort (the same as used in /3/) in form of a slotted hollow cylinder (made of 0.05 mm thick CuBe sheet) the mixer shows as video detector in the frequency range 290-300 GHz a responsitivity of 280 ± 50 V/W at a bias current of 3 microamperes and a chopping frequency of 1 kHz. Results in mixer operation will be reported in the future.

We have been developing the TEA CO₂ laser/D₂O laser system and the detection system for the ion Thomson scattering experiment on the Heliotron E device in Kyoto University. Up to now a considerable effort has been concentrated on the improvement of the laser output characteristics such as (i) output energy, (ii) pulse duration and (iii) spectral purity. Recently, we have succeeded in obtaining high power, single mode TEA CO₂ laser beams with good reproducibility, by developing a relatively compact TEA CO₂ laser system. It consists of a main laser oscillator (Lumonics 601) and a triple-pass amplifier (Lumonics 620). The main laser (601) is injection-locked by the output pulse from a hybrid laser consisting of a cw CO₂ laser section and a TEA CO₂ laser section (Lumonics K921S). The cavity length of the main laser (601) is feedback controlled by making use of the cw CO₂ laser signal, so that the single mode output is obtained with high probability. The output pulse duration of the main laser is also maximized by properly choosing the injection time after the initiation of the main discharge. The typical pulsewidth of the main laser in the case of the pulsed injection locking, is about 0.6 μs and the output energy is about 4 J at the line of 9R22. Then the laser beam is amplified by a triple pass amplifier up to 100 J . The burn patterns of the amplifier output beams show roughly uniform intensity distribution at the input window of the D₂O laser. The 4 m long, unstable D₂O laser consists of a set of concave and convex mirrors and a wire grid. We measured the output power of the D₂O laser with a Scientech power meter and the maximum power of 200 mJ was obtained at a pressure of about 5 Torr. The measurements of the D₂O laser emission linewidth were already carried out by the MIT ¹⁾ and Lausanne groups ²⁾. However, the detailed spectral structures of the D₂O laser were not obtained yet, because the frequency resolutions were limited to the bandwidth of filter used in their detection systems, say, 80 MHz, which are broader than the longitudinal mode spacings.

The set-up and capabilities of a VNA Wiltron 360 extension to the frequency range 70.5 - 82.5 GHz are reported. The swept signal (1.5 - 13.5 GHz) emitted by the test-set is up-converted (see Fig. 1) in a broadband mixer by a fixed local oscillator (BWO at 69 GHz). A 70 GHz cut-off filter (suppression of the carrier better than 80 dB causes an amplitude error less than 0.001 dB and a phase error less than 0.006 degrees /1/) behind the mixer allows only the upper sideband to pass, whose amplitude and phase information is known because the baseband serves as a reference (automatically in the test-set). After passing the device-under-test in transmission the signal in the frequency range 70.5 - 82.5 GHz is down converted to the baseband in a second mixer, which is pumped by the same local oscillator via a flexible phase stable (see Fig. 2) dielectric fiber with corresponding transitions to rectangular waveguide (see Fig. 3). So geometrical lengths of devices up to 25 cm can be compensated and different geometrical positions of the ports, too. This is a significant improvement related to rigid rectangular waveguide for compensation /2/ and also related to a proposed quasi- optical line stretcher /3/. After amplifying this signal is fed in the test-set of the VNA. Because the up and down conversion is done by the same source, no problems (e.g. source locking, measurement of high Q-factors) occur in spite of a FM deviation of nearly 1 MHz of the local oscillator. A noise floor of -80 dB relative to a thru calibration (at minimum bandwidth and 512 points averaging) is achieved, although not optimized single ended harmonic mixers, which require directional couplers to separate and combine the signals, respectively, are used in the fundamental up and down mixing operation. A second problem caused by using single ended mixers in reflection is the cross-talk via the dielectric fiber. So three isolators (isolation better than 75 dB) are provided to suppress the cross-talk. Furthermore the amplitude and phase reproducibility is better than 0.1 dB and two degrees, respectively (see Fig. 4).

This paper presents a unique design concept for a dual-frequency,electronically steerable, MM-wave phased array antenna using Monolithic Microwave Integrated Circuit (MMIC) technology. Such an antenna design will be found most attractive for satellite communication and missile seeker applications, where size, weight and power consumption are the most stringent requirements. The block diagram of a dual-frequency (20 GHz/30 GHz), electronically steerable, phased array antenna using MMIC technology is shown in Figure 1. Specific details on the critical RF components are also shown in Figure 1. Because of the location of the radiating elements on the hemispherical surface, the antenna is inherently capable of providing electronic scanning over 360 deg. in AZ-plane and over plus/minus 60 deg. in EL-plane. This electronically steerable phased array antenna will generate multiple beams in the AZ-plane with consistent bandwidth and pattern symmetry. This design exploits true integration of printed circuit antenna technology, GaAs active device technology, MM-wave microstrip technology and printed circuit time delay phase shifting element technology. This design employs microstrip periodic structure transmission line sections as time delay phasing elements, which requires no input power. The printed circuit microstrip line sections will be used as feed networks. Two distinct dual- frequency, antenna element fabrication techniques, namely, stacked-patch element (Figure 2a) and collocated, interleaved-patch element (Figure 2b), were investigated in terms of cost, size, performance and complexity. Tradeoff studies performed seem to indicate that stacked-patch element approach will offer minimum size and weight. The physical dimensions shown in Figure 1 and 2 are computed for 20 GHz and 30 GHz operations. All the electronics, control circuits and RF MMIC circuits can be located within the hemispherical structure. The input power, overall system size and weight will depend on the antenna gain requirement, inter-element spacing, number of elements and phase shifter types. It is important to mention that delay line phasing networks using printed circuit periodic structures will provide optimum flexibility in phasing of the antenna elements with minimum loss. The proposed antenna architecture for a dual-frequency operation using a common aperture and MMIC technology seems to offer an antenna system with minimum cost, size, weight and power consumption.
