Design of a photonic band gap polarizer

Abstract

We explore the application of photonic band gaps (PBGs) in photonic crystal structures to propose the design of an ultracompact PBG polarizer. The existence of complete PBGs in certain photonic crystal structures and the variation introduced in the PBGs by the creation of defects has been utilized to design a PBG polarizer at 1.55μm with a degree of polarization equal to 1 leading to the formation of a super polarizer. © 2006 Society of Photo-Optical Instrumentation Engineers.
