DOUBLE-CLAD FIBER COUPLERS

The double-clad couplers developed by Castor combine single-mode light transmission with multimode light transfer. Light transmission in the core is quasi-lossless from Port A to Port S, and again from Port S to Port A (see diagrams below). In the inner cladding of the double-clad fiber, light transfer occurs from the inner cladding of Port S to the multimode branch called Port B in couplers designed for light collection. ...
