Abstract

The use of a vortex phase optic as a coupling element for a dual mode step index fiber system is presented. We introduce a novel but rather simple coupling scheme for selectively exciting the LP11 mode in a step index fiber that is a single mode at a longer wavelength. This scheme can be utilized to optically pump fiber lasers and amplifiers.
