Abstract

Many optical systems are based on the polarization state of light (e.g., the magneto optical disk). Others may be optimized using polarized light (e.g., the capacity of optical communication systems may be doubled). For such systems polarization depending optical elements are needed. Polarizing computer generated holograms (PCGH) may allow the integration of different functions in one element. They should help to simplify existing systems and open up new applications. We propose the fabrication of PCGHs based on micro structuring of polarizing or birefringent materials. A method of calculation of the PCGH transmission function is described. A simple and useful method for production of binary and grayscale amplitude PCGHs is shown. Experimental results demonstrating the possibilities of our approach are presented. Possible applications are discussed.
