OPTICAL SYSTEMS COMPRISING MULTI-CORE OPTICAL FIBERS FOR REALIZING DIRECT CORE TO CORE COUPLING

摘要

A multi core optical fiber that includes a plurality of cores disposed in a cladding. The plurality of cores include a first core and a second core. The first core has a first propagation constant β₁, the second core has a second propagation constant β₂, the cladding has a cladding propagation constant β₀, and (I).
