Theoretical examination of waveguide polarizer with periodic dielectric multiplayer

Abstract

Waveguide polarizers with a high extinction ratio can be formed for integrated optics by using artificial birefringent media. In this paper, we describe the design and theoretical characteristics of TM-pass waveguide polarizer using periodic dielectric multiplayer. The designed TM-pass waveguide polarizers in the length of 5 mm and thickness of 10 μ m have the extinction ratio of 20 dB and over and the insertion loss of 0.1 dB and under. In addition, we designed a more practicable structure using an adhesive layer.
