Title: Oam mode demodulation system based on mode conversion
Inventor: GUO ZHONGYI
IPC: H04B10/112
Filed: 2018-11-05
Abstract: The present invention provides an OAM mode demodulation system based on mode conversion, the present invention combines a pattern classifier and a device of a Mach Zehnder interferometer embedded with a Dove prism to avoid the inherent defects of the pattern classifier. Due to parity topological charge classification of the improved Mach Zehnder interferometer, the adjacent topological charge spacing in the output beam of each port is at least larger than or equal to 2, and therefore, the overlap and crosstalk brought by the pattern classifier itself can be avoided. The pattern classifier itself is a relatively efficient, parallel detection method, adding an improved Mach Zehnder interferometer before pattern classification can increase the channel utilization while solving the inherent overlap.
