Abstract

A systematic review of the architectural framework, key technological breakthroughs, and future development trends in satellite optical communication is presented in this paper. An analysis of the limitations of conventional radio frequency (RF) communication in fulfilling the increasing demands for high data rates, large capacity, low latency, and high reliability in space-based applications is needed. This study emphasizes that laser communication, which has exceptional advantages such as ultrawide bandwidth, strong anti-interference capability, low power consumption, and high security, has become a strategic focal point in international space communication development. The composition and working principles of satellite optical communication systems are expounded upon. Case studies regarding low-Earth orbit (LEO) satellite networks and deep-space exploration communication links are utilized to examine key design considerations and performance constraints across diverse application scenarios. At the core technological level, an analysis of the principles, recent advancements, and challenges of several critical technologies is carried out, including high-power lasers with advanced modulation, high-sensitivity reception, precision beam pointing–acquisition–tracking (PAT), atmospheric channel compensation, and Doppler shift compensation. Emerging research frontiers, such as AI-driven dynamic link optimization, integrated space–air–ground optical networks, intelligent adaptive modulation, and the integration of quantum communication, are emerging. This work offers a theoretical basis and technical reference for constructing global, efficient, and reliable space information networks.
