Abstract
An optical fiber having an improved input fiber end for an optical isolator. The end of the fiber has a flat end surface substantially perpendicular to the longitudinal axis of the fiber. An optical barrier layer, formed by a layer of chromium and a layer of gold, covers the end surface of the fiber with an aperture exposing the core and covering the cladding of the fiber. Light transmission into the end is substantially reduced to increase the reflection loss of the optical isolator.
