The rapid advance of optical communication technology requires improvements in data transmission capacity and efficiency. Conventional methods of increasing the transmission capacity such as polarization,wavelength, and spatial mode division multiplexing have shown significant promise, while spatial mode division multiplexing(SDM) offers a new approach through the use of orthogonal spatial modes as distinct communication channels.
