Abstract

The invention relates to an optical communication system based on hybrid mode multiplexing, specifically an optical communication method and device based on hybrid mode multiplexing. The method comprises the steps that optical signal modulation units generate single-wavelength fundamental mode modulation output optical signals under modulation of a baseband data signal; hybrid mode multiplexing optical signals are formed; the hybrid mode multiplexing optical signals are transmitted in a transmission medium, and hybrid mode multiplexing output optical signals are generated; single-wavelength channel or wavelength division multiplexing multichannel fundamental mode output optical signals are formed according to the hybrid mode multiplexing output optical signals; multi-way single-wavelength channel fundamental mode output optical signals are formed according to the wavelength division multiplexing multichannel fundamental mode output optical signals; each single-wavelength channel fundamental mode output optical signal passes an optical signal modulation unit, thereby outputting transmitted data information. According to the method and the device, mode resources of a free space or communication transmission few-mode optical fibers are utilized fully, mode utilization rates can be improved to the greatest extent, and the transmission capability and transmission performance of an optical communication system are increased.
