摘要

我们提出了一种基于多量子阱(MQW)的高速光电探测器，其对TE偏振光的响应率为0.76 a /W，偏振消光比(PER)在波长为1550 nm时为4.5 dB，在波长为1580 nm时为20 dB以上。由于最小化了价带偏移和优化了量子波数，光电二极管显示出36 GHz的高3db带宽。

High-Speed Multiple Quantum Well Photodetector for Polarization Diverse Detection

We present a Multiple Quantum Well (MQW) based high-speed photodetector with a responsivity for TE polarized light of 0.76 A/W and a polarization extinction ratio (PER) of 4.5 dB at a wavelength of 1550 nm and above 20 dB at 1580 nm. As a result of minimizing the valence band offset and optimizing the number of QWs, the photodiode shows a high 3dB-bandwidth of 36 GHz.
