CLADDING MODE STRIPPER

摘要

An improved arrangement for stripping stray light energy that is propagating in the cladding layer of an optical fiber is provided. A cladding light stripper is provided that incorporates removal of at least a portion of the coating material and/or splicing the fiber to a fiber of differing diameter and/or having a bend of constant or decreasing or varying radius to efficiently remove cladding light while distributing heat dissipation in a controlled design across the device with respect to a specific direction of input (cladding) light.

主权项

1. A system for removing cladding mode light comprising:
an optical fiber having at least an elongated core surrounded by one or more cladding layers, the cladding having a lower refractive index relative to the core and a coating layer having a lower refractive index relative to the cladding, wherein cladding mode light propagates within said cladding; said optical fiber having at least portion of said coating removed along a predetermined length thereof; and said optical fiber being bent along said predetermined length.
