摘要

我们报道了一种新型的基于InP的行波放大光电探测器，其外量子效率超过100%。我们的探测器垂直结合了大块InGaAs光电探测器脊区和横向受限的InGaAsP量子阱，用于放大。除了超高的响应能力外，这种探测器还具有实现高饱和功率和高速的潜力。用先进的数值模拟方法讨论了器件的物理特性。

InP-based waveguide photodetector with integrated photon multiplication

We report on novel InP based traveling wave amplification photodetectors exhibiting an external quantum efficiency of more than 100%. Our detectors vertically combine a bulk InGaAs photodetector ridge region with laterally confined InGaAsP quantum wells for amplification. In addition to ultra high responsivities, such detectors have the potential to also achieve high saturation power and high speed. The device physics is discussed using advanced numerical simulation.
