Heterodyne Characterization of High-Speed Photomixers for the Ultraviolet
Abstract
A detailed experimental and theoretical investigation of high-speed photodiodes is presented. Detector geometries included both planar and interdigitated designs with gap widths of 1.0, 3.0 and 4.5 microns. Detailed photomixing measurements were performed using a ultraviolet heterodyne system operating at 334.5 nm. Measurements included frequency response to 10 GHz as a function of beam position, bias and optical power. Limited measurements were made to 18 GHz. A detailed, first principles, model of msm-photodiode frequency response including carrier drift velocity, diffusion, recombination and beam position is derived. Including packaging effects, good agreement was found between the experimental results and the model. Theses.
