Short Polarization Filter in Pillar-Based Photonic Crystals

The strong polarization dependence of two- dimensional photonic crystals is exploited for polarization filtering. The device with a length of 3.9 mum is integrated in a photonic integrated circuit based on InP waveguide technology. The average transmissions in the wavelength range from 1530 to 1570...

Description
Summary:The strong polarization dependence of two- dimensional photonic crystals is exploited for polarization filtering. The device with a length of 3.9 mum is integrated in a photonic integrated circuit based on InP waveguide technology. The average transmissions in the wavelength range from 1530 to 1570 nm are -8.7 dB for transverse-magnetic polarization and -26.5 dB for transverse-electric polarization.
