Abstract: A mounted polarizer and corresponding assembly method is provided. The mounted polarizer includes a substrate, and a polarizer with a plurality of parallel wires mounted on a supporting base. An epoxy binds the polarizer to the substrate, such that the plurality of parallel wires is mounted between the substrate and the supporting base, and the epoxy is in direct contact with the plurality of wires. The substrate, the epoxy and the supporting base all have a substantially matching refractive index. The mounted polarizer substantially transmits one polarization of light, and substantially blocks transmission of another polarization of light.

Abstract: Techniques are used to determine when interfering beams of light are precisely aligned at the core of the fiber when a laser interferometer is used to burn diffraction gratings into optical fibers. Two alternative methods are disclosed for performing this function, namely, refraction of the UV fluorescence through the fiber onto a paper or screen, and alternately interrupting the left and right UV beams, then directly observing the fluorescence pattern of the UV beam on the fiber core to determine alignment.
