Abstract: We present a theoretical analysis of the quantum efficiency of a resonant cavity enhanced InGaAs/GaAs P-i-n photodetector (PD) for the ultrashort optical connections. The numerical method of calculation of quantum efficiency combining a transfer matrix method and an energy conservation law is offered. Using anomalous dispersion (AD) mirror flattopped QE spectrum has been obtained. Conditions for ideal flattopped spectral response have been received. A design with a maximum QE of 93.5% and 3 nm bandwidth at 0.02 dB below the peak is presented.
