POLARIZING HOLOGRAPHIC BEAM SPLITTER ON A PHOTORESIST

A method to take advantage of high-spatial-frequency surface-relief gr atings as polarizing beam splitters is described. The analogy between that kind of grating and a volume grating is the basis of the theoreti cal predictions. Results of rigorous calculations are presented. High polarizing performances are demonstrated. We illustrate the method wit h a practical realization that checks the validity of the calculations . (C) 1995 Optical Society of America
