Abstract

Recently we have experimentally demonstrated pulse compression and soliton formation in fiber Bragg gratings.^1,2 These effects occur through the interplay between the optical nonlinearity and the grating dispersion associated with the strong coupling between forward and backward propagating modes. In this paper we report for the first time, we believe, the observation of optical switching and pulse reshaping in a long period grating that couples the light between the copropagating core and cladding modes.
