Paper Abstract

A new concept polarizer using a birefringent diffraction grating has been developed. The operating principles and fabricated polarizer characteristics are described. The fabricated element has more than 20 dB extinction ratios for both polarization lights which are sufficient for use in optical disk heads. The polarizer is easily mass manufactured by the planar batch process. A holographic optical element that is combined with this polarizer function is proposed. Applications of the holographic optical element for an optical disk read/write head are also described.
