abstract

• For infrared imaging systems the most used detectors are microbolometers. The trend is to create focal plane array (FPA) sensors composed of smaller and smaller infrared pixels, but this reduction decreases the efficiency of traditional bolometers. Optical antennas have been studied as an option to replace traditional bolometers, but they require a bias voltage and a rectification system. Recently, nanoantennas with thermoelectric elements have been incorporated to provide a continuous output voltage, reducing part of the energy of the entire infrared imaging system. In this work, Seebeck nanoantennas are modeled as an infrared pixel for FPA, and their response and effectiveness are calculated using finite element simulation. © 2022 SPIE.
