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.
期刊介绍:
Technical Physics Letters is a companion journal to Technical Physics and offers rapid publication of developments in theoretical and experimental physics with potential technological applications. Recent emphasis has included many papers on gas lasers and on lasing in semiconductors, as well as many reports on high Tc superconductivity. The excellent coverage of plasma physics seen in the parent journal, Technical Physics, is also present here with quick communication of developments in theoretical and experimental work in all fields with probable technical applications. Topics covered are basic and applied physics; plasma physics; solid state physics; physical electronics; accelerators; microwave electron devices; holography.
