Photon Statistics and Spectral Selectivity Limits of Thermal Detectors

Abstract

The specific goals of this proposal are to: 1) Model and measure the contribution of Bose-Einstein statistics to the photon noise of radiation-limited thermal detectors, for both single radiation mode and multi-mode detectors. 2) Theoretically and experimentally quantify the dominant phenomena that cause uncertainty or fluctuations in the rest position of a thermal detector. For devices with high sensitivity and spectral resolution, these will, at a minimum, include photon counting noise, and thermomechanical noise. 3) Develop radiation noise theory for extremely narrow spectrum thermal detectors that includes an accounting of the cavity-altered density of states. Experimentally, this provides an intriguing opportunity to study how modes internal to the detector couple to free space modes.
