Paper Abstract

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.
