Description

technical field

[0001] The invention relates to the field of resonant optical communication, in particular to a multi-user resonant optical communication system and method based on frequency division multiple access. Background technique

[0002] In order to meet the needs of future communication development and realize high-speed broadband wireless communication, it is necessary to develop new spectrum resources in high-frequency bands. Since the wavelength of light waves is short and has a frequency of hundreds of THz, using light as a carrier of wireless communication is bound to become an important technical means of wireless communication in the future. Using resonant cavity to form stable light beam and using it as a carrier to realize wireless communication is an emerging wireless optical communication technology. This technology not only has a high transmission rate, but also has good mobility. A technology that breaks through the bottleneck in the development of wi...
