Analysis on a Flattop Response Resonant Cavity Enhanced (RCE) Photodetector

This paper discussed a novel resonant cavity enhanced (RCE) photodetector with a flat-top response, which is promising for WDM application. We analyzed and compared the response curves and crosstalks of the novel RCE and conventional RCE photodetectors, and the influences of the layer-thickness errors on the response curves of the flat-top response RCE photodetectors, and the dependencies of the flat-top RCE photodetector's response on incident angle and polarization were also given.
