Mode conversion based on the periodic coupling by a reflective fiber grating.

Abstract

The periodic mode coupling between the LP(01) and counterpropagating LP(02) modes induced by a reflective fiber grating is investigated by using the coupled-mode theory. The properties of the mode conversion by the reflective fiber grating are compared with those by a transmissive grating that couples LP(01) and LP(02) modes in a same direction. Our results show that the former has a narrower power conversion spectrum than the latter.
