Abstract

We present an overview on the progress of InP/InGaAs based Hi-Lo APD's, which are important for long-haul optical fiber communications. Much of recent research efforts have been focused on improving the operation reliability, the gain- bandwidth (GB) product, and reducing the excess noise factor. To achieve a high GB product and a reliable operation, the reduction of the thickness of the multiplication layer and an optimum design of the internal electric field distribution are essential. The concept of the planar InP/InGaAs APD is very important from this perspective and the Hi-Lo APD's are expected to play an important role.
