Paper Abstract

In order to resolve the trade-off between quantum efficiency and response speed in resonant cavity enhanced (RCE) photodiode, the scheme of the transparent and unique pattern ohmic contact (TUPOC) microstructure was proposed. This scheme can be used for improving device's response speed by reducing the diode capacitance without influencing quantum efficiency. Three kinds of the TUPOC microstructures were proposed and simulated, the first one was realized. The response speed of the finished device with mesa area of 50×50μm2 is remarkably increased, 3dB bandwidth of 18GHz has been demonstrated, but the device without the TUPOC microstructure only have 3dB bandwidth of 9.47GHz.
