ABSTRACT:
An optical waveguide Bragg grating spectrally selective reflector is made by ion beam implantation through a photolithographic mask to raise locally the effective refractive index of the guide. This contrasts with the standard method, which uses UV light to raise the index through the agency of the photo-refractive effect.
