Abstract
The issues related to the development and manufacturing single photon detector based on single-photon avalanche photodiodes (SPAD) InP/InGaAs/InP, operating in Geiger mode on telecommunications wavelength 1550 nm are discussed. A description of the SPAD design is given. The method of obtaining the InP/InGaAs/InP heterostructure by molecular-beam epitaxy, methods of manufacturing SPAD chip by planar technology, features of selective doping with zinc p-regions in the InP layer and developed electronic schemes for measurement main parameters of SPAD are described. Preliminary results of measurements SPAD parameters are presented.
