Development and study of a model of an autonomous energy information station of free space optical communication

Abstract

A model of an autonomous receiving station of free space optical communication system based on a multi-section energy heterostructure (HJT) Si photoconverter and an information photodetector based on AlGaAs/GaAs p-i-n photodiodes has been developed. The energy part, when excited by laser radiation with a power of ~ 264 W at a wavelength of 0.974 μm in the photovoltaic mode, provided ≥ 60 W of electric power. The photodetector of the information channel, when excited by pulsed radiation at a wavelength of 0.78 μm, provides response time in the photovoltaic mode in the sub-nanosecond range.
