Abstract

A novel design of a compact and integrated transverse-magnetic-pass optical waveguide polarizer in InGaAsP-InP for use with a telecom wavelength window is presented. The polarizer is realized by integrating an air-hole-type photonic crystal waveguide in a honeycomb lattice geometry. For 20-μm-long polarizer devices with two different lattice constants a = 350 and 590 nm, the flat bandwidth and the measured polarization extinction ratio are ~ 80 nm, 16 dB and ~ 50 nm, 16 dB, respectively.
