Ultra-high speed p-i-n/HBT monolithic OEIC photoreceiver

An extremely wide-bandwidth monolithic OEIC receiver with high gain and low noise is described. It demonstrates the ability of HBT technology to provide low-noise and high-bandwidth performance in a preamplifier combined with an easily and naturally integrable optical detector. A circuit topology is also demonstrated to yield good high-speed performance with GaAs-AlGaAs HBTs. With minor modifications and improvements both speed and quantum efficiency should be easily increased. This approach can be extended into the InGaAs-InAlAs or InGaAs-InP system to provide operation at 1.3 and 1.55 mu m.
