Photonic Crystal Polarizing Optical Components

Half-Mirror Polarizer for Laser Cavity

Reflectivity for each polarization can be tuned separately. As a half-mirror in a laser resonance cavity, the element is used to generate and select the output polarization of the laser. Because of its inorganic nature, the element can withstand very high optical power.
