Abstract
Resonant Cavity Enhanced (RCE) photodiodes may have advantages over the conventional p-i-n photodiodes due to an enhancement of the quantum efficiency obtained from the constructive interference of the light waves that are made to oscillate in a cavity. In this paper a novel RCE structure, with applications in long wavelength optical communication systems, is proposed and its frequency response is investigated and compared to that obtained for conventional p-i-n devices. An optimization procedure is implemented and the results show that these RCE photodetectors may have bandwidths larger than 80 GHz and a bandwidth-quantum efficiency product above 80%.
