A Variable Cavity-Length Resonant Cavity Enhanced (RCE) Photodetector with Flat-Top and Steep-Edge Response
This paper presents a novel resonant cavity enhanced (RCE) photodetector with flat-top and steep-edge response. The response is obtained by dividing the filter cavity into ten parts with different length. The quantum efficiency of the photodetector is more than 80％ in bandpass, the ripple of the flat top is less than 2％, and 0.5 dB, 3 dB, and 20 dB bandwidth is 0.32 nm, 0.46 nm, and 0.92 nm respectively, which meets the requirements of DWDM system. Compared with similar photodetectors, this photodetector has high quantum efficiency, narrow spectral response linewidth and good flat-top and steep-edge response.
