Quasi-resonant cavity enhanced photodetector with a subwavelength grating
文献摘要：
We designed a tunable wavelength-selective quasi-resonant cavity enhanced photodetector(QRCE-PD]based on a high-contrast subwavelength grating(SWG].According to simulation results,its peak quantum efficiency is 93.2％,the 3 dB band-width is 33.5 GHz,the spectral linewidth is 0.12 nm,and the wavelength-tuning range is 28 nm[1536-1564 nm].The QRCE-PD contains a tunable Fabry-Perot[F-P]filtering cavity[FPC],a symmetrical SWG deflection reflector[SSWG-DR],and a built-in p-i-n photodiode.The FPC and the SSWG-DR form an equivalent multi-region F-P cavity together by multiple mutual mirroring,which makes the QRCE-PD a multi-region resonant cavity enhanced photodetector.But,QRCE-PD relies on the multiple-pass absorption enhanced effect to achieve high quantum efficiency,rather than the resonant cavity enhanced effect.This new photodetector structure is significant for the application in the dense wavelength division multiplexing systems.
