Paper Abstract

We report on the fabrication and characterization of interdigitated finger, optical detectors/mixers. These devices are used in an FM/cw ladar system to detect and demodulate low intensity amplitude-modulated optical signals. Three different types of interdigitated finger structure were tested and compared in this study. We also present a theory to explain the asymmetry observed in the devices and discuss its implication in an FM/cw ladar application.
