Abstract: A method of modifying birefringence properties of a waveguide formed within a carrier, the method comprising the steps of inducing a stress anisotropy in the waveguide and effecting a differential decrease in a first refractive index of one mode in the waveguide with respect to a second refractive index of another mode of the waveguide.

Abstract: A single longitudinal mode narrow linewidth and low threshold all fiber laser arrangement is disclosed, constructed from a ring cavity, a gain portion in the ring cavity, an input-output coupling interposed within the cavity and pumping means connected to the ring cavity and to the grating such that, upon actuation of the pumping means, the arrangement acts as a laser.
