Abstract

Three types of photodiodes with two-coordinate sensibility on the basis of InP-InGaAsP heterostructures are presented in the paper. The heterostructures optimization for selective receiving of radiation and their manufacturing technology are described. The photoreceivers narrow spectrum of photosensibility with maximum for λ = 1.06 μm excludes the influence of optic background upon the photoanswer and removes the necessity of supplemental interference filters utilization. The presence of a central photodector permits to receive unitary optic signals with duration < 10 ns and high frequency optic information (f > 1 GHz). The influence of X-rays upon the photoreceiver main parameters was studied. The main characteristics and parameters of realized devices are given, they show the efficiency of used technical decisions and the possibility of successful using of these devices in communications through atmosphere.
