We have numerically investigated the guiding properties in a hybrid polymer/silica photonic crystal fiber (PCF). We
considered poly-dimethylsiloxane (PDMS) as the infused polymer into the air-holes of PCF and we present how the
modal properties of the fiber are affected due to PDMS inclusions. We numerically calculated the guiding and thermal
properties of the hybrid structure in terms of the effective index, single-mode operation, confinement loss, numerical
aperture (NA), effective modal area (EMA) and fraction of power into the polymer-filled cladding for different relative
hole sizes, d/Λ (0.35-0.75) of the hybrid PCF whereas direct comparison with a conventional air-filled PCF is also
shown. Further investigation of EMA, NA and fraction of power in the cladding with respect to thermal variations is also
reported for a range of temperatures from 0°C to 100°C.
In this work, we demonstrate the formation of Poly-dimethylsiloxane (PDMS) films inside the holes of conventional
silica photonic crystal fiber. The index guiding properties of the new PDMS-layer/Silica structures were investigated and
optimized numerically using FDTD analysis. Films with thicknesses ranging from 100nm to 1μm were formed using
different PDMS solution concentrations and different solution movement speeds. The thickness of films was very
uniform along almost all the deposition length as indicated by Scanning Electron Microscopy (SEM) images and micro-
Raman mapping.
In this work, we demonstrate numerically and experimentally the temperature dependence of a photonic crystal fiber
(PCF) infiltrated with PDMS elastomer. We investigated the guiding properties of the PDMS-filled PCF and we present
the variation of the effective index and effective modal areas of the fundamental guiding mode at 633 and 1550 nm, for a
range of temperatures from 20°C to 75°C. Experimental measurements have shown an up to ~6% power recovery of the
bend-induced loss for a 6-cm long PDMS-filled PCF at 4 cm bend diameter.
In this work, we demonstrate a highly birefringent (Hi-Bi) photonic crystal fiber (PCF) infiltrated with PDMS elastomer
in order to enhance the sensitivity of the fiber to external temperature variations. Index guiding mechanism of the new
PDMS/Silica structure and birefringent properties were investigated numerically and experimentally. We investigated
the temperature dependance of birefringence from 20-120°C. For the particular design of Hi-Bi PCF, the cut-off
operating wavelength of the hybrid fiber was found to be around 750 nm. We also experimentally demonstrate the effect
of the elastomer inclusions to the polarization of the fiber. The sensitivity of the PDMS/Silica Hi-Bi fiber was found to
be ~ 0.37 rad/K/cm for temperatures ranging from 20 to 80°C. The total length of the hybrid PCF examined was about
1.4 cm.
We demonstrate a highly stable, all-polarization-maintaining fiber semiconductor ring laser source. It uses a semiconductor optical amplifier (SOA) to provide both gain and gain modulation from an external 5-GHz optical pulse train. The laser source generates 3.5-ps pulses up to a 50-GHz repetition rate with negligible amplitude pattern.
