ABSTRACT:
An optical fiber has a beveled end surface and a Bragg reflector grating formed on the end surface to form a single mode reflector for a semiconductor laser. A transmission fiber with a beveled end is fused to the beveled grating to form a continuous transmission line having an internal reflective grating.
