Composite-field MIC-PDs for low-bias-voltage operation

Abstract

A novel maximized-induced-current-photodiode (MIC-PD) structure with a composite field depletion layer achieves high responsivity of 0.8 A/W and a wide 3-dB bandwidth of 30 GHz at a low reverse bias voltage of 2 V for optical input power of +7 dBm.
