Abstract
The invention belongs to the technical field of optical communication, and discloses a multi-core optical fiber multiplexing and demultiplexing device and method based on a metasurface lens. For a light beam emitted by each fiber core of a multi-core optical fiber, the metasurface lenses manufactured on the two sides of a substrate are respectively used for turning and focusing, the light beam iscoupled to a plurality of single-core optical fibers, and a demultiplexing function of the multi-core optical fiber is realized; and the process is reversible, and a multiplexing function is realized.The device and the method solve the problems of higher cost and larger volume of space division multiplexing / demultiplexing in the prior art, and have the advantages of being compact in structure, low in cost and suitable for various polarized light.
Description
technical field [0001] The invention relates to the technical field of optical communication, in particular to a multi-core optical fiber multiplexing and demultiplexing device and method based on a metasurface lens. Background technique [0002] Facing the coming crisis of optical fiber transmission capacity, space division multiplexing technology using multi-core optical fiber for signal transmission has become a research hotspot. The space division multiplexer / demultiplexer is a key optical device in the multi-core optical fiber space division multiplexing technology. Its function is to couple the optical signal in the single-core optical fiber to each core of the multi-core optical fiber, and after transmission Spatial demultiplexing and multiplexing of signals in multi-core fibers into corresponding single-core fibers. [0003] At present, the existing space division multiplexing / demultiplexing methods include fusion taper method, lens coupling method, optical fiber bu...
