Abstract :
Experimental results are presented for a resonant cavity enhanced photodetector operating at 2 μm based on absorption in a single, strain-compensated, In0.83Ga0.17As quantum well. The device exhibits a selectivity of 9 nm, and 18% quantum efficiency. InP/InGaAs and Si/SiO2 material systems are used for the bottom and top Bragg reflectors of the resonant cavity, respectively. The dark current densities are lower than 10-6 A/cm2 at 2 V reverse bias
