Abstract

Optical antennas serve as light detectors in the infrared when coupled to transducers. Distributed bolometers have been proposed and positively demostrated to produce an electric signal when light is inciding on it. These devices can be easily fabricated using only one e-beam lithography step. However, the choice of the material used to fabricate the antennas is of great importance to enhance the performance of these devices. In this contribution we present an optimized distributed bolometer. The auxiliary elmentes analyzed to provide the maximum possible response. This analysis is made using a multiphysics approach taking into account the electromagnetic and thermal domains.
