Design of optical waveguide polarizer using photonic band gap

A new design of optical waveguide polarizer based on photonic band gap has been presented. A numerical approach based on the finite difference time domain method has been used to analyze and design photonic band gap polarizer. The performance of the device is investigated in terms of degree of polarization and transmittance. Polarizer action is achieved by engineering the defect modes in photonic band gap structures.
