Abstract
An optical measuring device includes an optical detector for measuring an incident optical signal coupled to the detector by an optical fiber. The optical fiber and/or the optical detector comprise an interface between optical media with different refractive indices, e.g., a boundary surface, face or facet. The interface is angled with respect to the incident optical signal to reduce reflection in the direction of the incident optical signal. Because light transmitted with a polarization perpendicular to the plane of incidence of the optical signal has an intensity substantially equal to the intensity of light transmitted with a polarization parallel to the plane of incidence of the optical signal, the incident optical signal transmitted through the interface is substantially independent of the polarization direction of the incident optical signal.
