提出了一种适用于波分复用系统的具有平顶陡边响应的新型谐振腔增强型(RCE)光电探测器结构,模拟得到了量子效率从峰值下降0.5 dB的线宽1.8 nm,10 dB的线宽5.6 nm,20 dB的线宽10.4 nm,量子效率峰值99.7%,几乎没有凹陷的响应曲线.

This paper proposes a novel resonant cavity enhanced (RCE) photodetector with a flat-top and steep-edge response, which is promising for WDM application. The simulated response curve has a bandwidth of 1.8 nm at 0.5 dB down from the peak, 5.6 nm at 10 dB down from the peak, 10.4 nm at 20 dB down from the peak, and a peak quantum efficiency of 99.7%, the ripple in the flat-top is negligible.
