Abstract:The high performance wavelength demultiplexing photodetectors for optical wavelength division multiplexing (OWDM) systems were introduced and analyzed. This type of devices are required to have high-speed, high quantum efficiency and ultra-narrow spectral linewidth simultaneously. Furthermore, it should have wide range tuning for satisfying the flexibility, intelligentizing and integration of systems in the OWDM networks application. This type of devices include resonant cavity enhanced (RCE) photodetectors, four mirror and three-cavity wavelength-selective photodetector, one-mirror-inclined and three-mirror-cavity (OMITMiC) photodetector, external cavity tunable RCE photodetector, tunable RCE photodetector with built-in liquid-crystal layer， micro-electro-mechanical-systems (MEMS) tunable RCE photodetector and long wavelength RCE photodetector with InP/air-gap reflector and so on. Some devices mentioned above were also introduced in detail.
