COUPLED SYSTEM MULTI-CORE FIBER, COUPLING MODE MULTIPLEXER AND DEMULTIPLEXER, SYSTEM FOR TRANMISSION USING MULTI-CORE FIBER AND METHOD FOR TRANSMISSION USING MULTI-CORE FIBER

摘要

The multi-core fiber of the present invention uses a multi-core fiber configuration, compatible with the "coupled" operation mode in which coupling between cores is positively utilized, to carry out mode division multiplexing transmission via a multi-core fiber that contains multiple single-mode cores in one optical fiber. The multi-core fiber of the present invention uses a configuration in which mode multiplexing transmission is carried out using a multi-core fiber that contains multiple single-mode cores in one optical fiber, wherein multiple cores are strongly coupled intentionally to form a coupled multi-core fiber that makes the coupled modes correspond, one to one, to the transmission channels.
