Abstract

Microbolometers are the detectors most used in infrared imaging systems, these detectors have the disadvantage of being slow and require a bias voltage to operate, which increases the power requirements of the system. The current trend is to transition to low size, weight, and power (low SWaP) imaging systems. Seebeck nanoantennas are resonant elements made of two dissimilar thermoelectric materials tuned at a particular wavelength, when this wavelength is incident on the nanoantenna it induces a current that increases the temperature at the feed of the antenna generating a temperature difference that produces a Seebeck voltage. Due to the small size of the antenna and its low thermal mass Seebeck nanoantennas are considerably faster than traditional bolometers. Also, since the thermoelectric elements provide an output voltage no bias is needed for operation, reducing the power requirements of the whole imaging system. Previous work has reported the use of antennas traditionally used in the microwave region of the electromagnetic spectrum as Seebeck nanoantennas, these antennas are polarization dependent which is not usually desired in infrared imaging systems. In this work a multipolarized Seebeck nanoantenna is analyzed as a potential infrared pixel, their responsivity and detectivity are calculated from Multiphysics simulations for different pixel sizes.
