Abstract

The invention provides a communication system based on a sunshine direct pumped space optical carrier generator. The communication system comprises a sunshine aggregation segmentation module, a pumping work module and a modulation communication module. The sunshine aggregation segmentation module is used for aggregating sunshine energy, and after segmenting the sunshine energy according to different frequency ranges, transmitting the segmented sunshine energy to the pumping work module; the pumping work module is used for converting the segmented sunshine to multipath optical carrier waves; and the modulation communication module is used for modulating communication information to carrier waves generated by the pumping work module, and after shaping light beams, outputting the light beams. According to the system provided by the invention, the sunshine energy is utilized as the only energy source of the multipath optical carrier waves, the requirements for power and light beam indexes of conventional satellite optical communication are satisfied, and at the same time, the heat control problem and the low energy efficiency problem in a conventional electric pump light communication technology are reduced.

Description

technical field [0001] The invention relates to the field of optical communication, in particular to a communication system based on sunlight directly pumping a space optical carrier generator. Background technique [0002] The space laser communication system refers to an optical communication system that uses laser light waves as the carrier and the atmosphere as the transmission medium. Free space laser communication combines the advantages of optical fiber communication and microwave communication. It not only has the advantages of large communication capacity and high-speed transmission, but also does not need to lay optical fibers. progress. The atmospheric transmission laser communication system is a communication system composed of two laser communication devices, which transmit modulated laser pulse signals (sound or data) to each other, receive and demodulate laser pulse signals from each other, and realize duplex communication. [0003] In order to reduce the co...
