1. An angle-cleaved optical fiber apparatus comprising:

  • an optical light source for emitting light;

    at least one optical fiber comprising a plurality of cleaved facets disposed at an end of the at least one optical fiber,wherein a first facet of the plurality of cleaved facets is disposed at a different angle with respect to a longitudinal axis of the at least one optical fiber than a second facet of the plurality of cleaved facets;

    wherein the end of the at least one optical fiber is positioned with respect to the optical light source such that;

    the second facet of the plurality of cleaved facets is configured to reflect a portion of light from the optical light source into an internal core of the at least one optical fiber; and

    the first facet of the plurality of cleaved facets is configured to refract a portion of the light from the optical light source onto a detector.
