Polarization MicroOptics

Categories: µ-3D printing


Here we show the use of DLW for the fabrication of a miniaturized phase retarder element, a Fresnel Rhomb, which acts as a broadband quarter-wave plate. We show the integration of the Fresnel Rhomb onto a polarization-maintaining optical fiber, converting linearly polarized light from the fiber into circularly polarized light over a very broad spectral range.
