title: Realization of a polarizer employing the combined effects of birefringence and diffraction.
abstract: A polarizer that uses the combined effects of birefringence and diffraction has been realized experimentally. A sheet of calcite was taken as the substrate, and a series of grooves with a sawtooth profile was manufactured on its surface by optical grinding and polishing. The sample polarizer shows good polarizing performance in test. The measured extinction ratio is better than 2 x 10(-4) and can be improved further.
