Abstract

Lateral Asymmetry in cladding of the Photonic crystal (PhC) waveguides has been utilized to demonstrate a compact TM-Pass polarization filter. The filter, which covers the entire conventional `C'- band of telecom spectrum has a low insertion loss and gives ≈ 41 dB extinction ratio at 1550nm wavelength.
