Abstract

State-of-the-art mid- and long-wave infrared detectors (IR) are extremely sensitive and are widely used in military and civilian applications. However, these detectors are not able to provide polarization wavelength, directionality, or coherence length of an incident IR source. Our novel IR detector, thermoelectrically coupled nanoantennas (TECNAs), inherently provide these attributes based on their antenna nature. In our talk, we show that the receiving characteristics of TECNAs are determined by their relative position above a cavity etched into the substrate. Our experimental results are supported by simulations that show that TECNAS are capable to detect the directionality of an incident IR beam.
