Abstract

In view of growing interest in eye-safe, solid-state coherent lidars using Thulium- and Holmium-based lasers, it has become necessary to investigate the properties of wideband, two-micron detection devices and evaluate their performance as heterodyne detectors. For this purpose, a detector measurement system has been developed that is capable of measuring all the necessary detector parameters for optimal designs of optical heterodyne receivers and predicting their sensitivities.
