ANGLE-CLEAVED OPTICAL FIBERS AND METHODS OF MAKING AND USING SAME

Optical fibers comprising a plurality of cleaved facets disposed at one end are disclosed. First and second facets of the plurality of cleaved facets are disposed at different angles. The optical fiber with the plurality of cleaved facets splits light from an optical component between an optical fiber core and a detector such that a portion of the light may be tapped off for monitoring. The first cleaved facet is disposed at a first angle such that a first portion of the light from an optical component is totally internally reflected into the fiber core. A second cleaved facet can be disposed at a second angle that is less than the first angle so that a second portion of light from the optical component refracts through the second facet to a detector. Methods of forming and using angle-cleaved optical fibers having a plurality of cleaved facets are also disclosed.
