Abstract :
A theoretical analysis of the optical absorption and quantum efficiency (QE) in a resonant cavity enhanced InGaAs/GaAs P-i-n photodetector (RCE PD) is presented. Using anomalous dispersion (AD) mirror flattopped QE spectrum is obtained. The influence of the thickness and position of AD layer on the optical absorption and QE is shown and design with a maximum QE of 92.5% and 6 nm spectral flattop is presented.
