Abstract: A multiplexed optical communication system comprising a carrier optical fiber, a plurality of launching light sources, and a matching plurality of multiplexer/demultiplexers and photodetectors is described and claimed. Optical communication channel separation by Spatial Domain Multiplexing (SDM), Optical Angular Momentum (OAM) multiplexing, and Wavelength Division Multiplexing (WDM) is used in combination to achieve significant increase in optical communication channel bandwidth over the prior art. The launching light sources may be positioned such that the light beams are incident on the receiving end of the carrier optical fiber at desired angles including complementary angles. Crosstalk between optical communication channels is minimal. The communication bandwidth of a TDM system may be increased by an order of magnitude due the layered WDM/SDM/OAM data multiplexing of the invention.

Abstract translation: 描述并要求保护包括载波光纤，多个发射光源和匹配的多个多路复用器/解复用器和光电检测器的复用光通信系统。 结合使用通过空间域复用（SDM），光学角动量（OAM）复用和波分复用（WDM）的光通信信道分离，以实现现有技术中光通信信道带宽的显着增加。 发射光源可以被定位成使得光束以包括互补角度的所需角度入射在载体光纤的接收端。 光通信信道之间的串扰很小。 由于本发明的分层WDM / SDM / OAM数据复用，TDM系统的通信带宽可能增加一个数量级。
