Abstract

The optical components in the detection train of a conventional magneto-optical (M-O) disk head include a half-wave plate and a polarization beamsplitter. These polarization components are bulky and require specialized mounting hardware. In order to realize a more compact head, we propose that these elements be replaced by an integrated device composed of cascaded volume and surface-relief gratings. In this paper, we describe the proposed system, detail designs for the individual elements, compare theoretical and prototype element performance, and discuss the operational tolerances of these elements.
