Nanoantenna Integrated Thermomechanical Infrared Detector

We numerically studied the nanoantenna integrated thermomechanical mid-infrared detector working at room temperature based on bi-material structures. Three separate bilayer configurations are investigated and optimized for maximum thermomechanical deflection. The integrated optical nanoantennas are geometrically tuned to reach the highest optical absorption at 6 mu m. Thermal time constants and fundamental noise equivalent powers of the three bilayer configurations are also calculated. We also discuss the potential implementation of our detector in infrared polarimetry.
