Optical fiber having first and second reflective surfaces and method of operation

摘要

An optical fiber includes an endface having a first reflective surface and a second reflective surface. The first reflective surface is formed at a first bias angle with respect to a plane that is normal to the longitudinal axis of the optical fiber. The first reflective surface totally internally reflects an optical signal at a first reflection angle with respect to the longitudinal axis. The second reflective surface is coupled to the first reflective surface and formed at a second bias angle with respect to the plane such that the second reflective surface totally internally reflects the optical signal at a selected second reflection angle.
