Abstract

An optical apparatus comprises a dispersion compensating optical waveguide, and an optical pump that pumps the dispersion compensating optical waveguide with light. The light from the pump provides suitable selective gain to a fundamental mode of the dispersion compensating optical waveguide that multi-path interference is substantially reduced.A method of reducing multi-path interference comprises pumping a dispersion compensating optical waveguide with light to provide suitable selective gain to a fundamental mode of the dispersion compensating optical waveguide so that MPI from said dispersion compensating optical waveguide is significantly reduced.
