## Abstract We have demonstrated a monolithic and cost‐effective InP‐based resonant‐cavity‐enhanced photodetector with an InP/air‐gap distributed Bragg reflector (DBR) fabricated by using selective wet etching. Peak quantum efficiency is 54% at 1.57 μm, which corresponds to nearly two‐fold enhancem
