Abstract

A resonant absorption cavity that couples long-wavelength infrared (LWIR) light into a movable plate has been demonstrated for thermal detectors, especially microbolometers. Each device is continuously tunable over 8.7 11.1 μ m by using electrostatic actuation with voltages from 0 to 42 V . The width of the resonance is relatively broad, approximately 1.5 μ m , to match the large widths of many spectral features in the LWIR. At an actuation voltage of 45 V , the device switches into a broadband mode with an absorption width of 2.83 μ m . This latter mode is used to enhance sensitivity in low-light situations in which little spectral information is present.
