Abstract
A polarizer which works upon the combination effect of birefringence and diffraction has been designed and realized experimentally. According to the design the polarizer may be consisting of a sheet of birefringent material or two birefringence plates, on which surface one dimensional grooves with a sawtooth profile or echelon profile are carved. In experiment, a periodic grooves of a sawtooth profile were fabricated on the surface of calcite plate by mechanical and optical manufacture techniques. This sample polarizer was test for its polarized feature with a non-polarized HeNe laser, and the results show the polarizer is of a good polarized performance.
