We report on novel InP-based traveling-wave ampliÞcation photodetectors exhibiting an external quantum efficiency of more than 100%. Our detectors vertically combine a bulk InGaAs photode- tector ridge region with laterally conÞned InGaAsP quantum wells for ampliÞcation. 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.
