Abstract
A model of an autonomous receiving station of free space optical communication station 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 ~264W at a wavelength of 0.974µm in the photovoltaic mode, provided ≥60W of electric power. The photodetector of the information channel, when excited by pulsed radiation at a wavelength of 0.78µm, provides speed in the photovoltaic mode in the sub-nanosecond range.
