Abstract
Interdigitated metal - semiconductor- metal (MSM) photodetectors with sub-micron electrode spacing offer ultrafast response time and high responsivity1 for use in optical fiber communications, but are limited by parasitic capacitance and polarization effects. In this work we investigate the effect of electrode dimension on the polarization sensitivity, bandwidth and responsivity, and demonstrate a new polarization-insensitive photodetector.
