Abstract

The invention discloses a multi-user laser communication system and a method with flexible beam control, and the system comprises a multi-beam optical phased array antenna, a multi-wavelength light transmitting module, and a multi-wavelength light receiving module. The multi-wavelength light emitting module outputs a digitally modulated light signal and sends the light signal to the multi-beam optical phased-array antenna, and the multi-beam optical phased-array antenna emits the digitally modulated light signal; the multi-beam optical phased array antenna receives an optical signal and sendsthe optical signal to the multi-wavelength optical receiving module, and the multi-wavelength optical receiving module demodulates the optical signal to obtain a digital signal. The invention has theadvantages of small size, high integration level and multi-beam flexible control.

Description

technical field [0001] The invention belongs to the technical field of satellite laser communication, and in particular relates to a multi-user laser communication system and method with flexible beam control. Background technique [0002] In recent years, space laser communication technology has developed rapidly, and foreign countries have successfully established inter-satellite and satellite-ground high-speed laser communication demonstration verification systems. With the development of space laser communication technology, the inter-satellite laser communication link is developing into a space laser communication network, which requires communication between one user and multiple users. The currently researched optical phased array antenna mainly realizes beam scanning control, and there is no integrated optical phased array antenna laser communication terminal for transmitting and receiving, which makes the integration degree low, the volume large, and the beam is not...
