General Optics
Birefringent Wedges
Split or combine polarization-multiplexed optical signals in telecom systems with miniature birefringent wedges offering both high extinction ratio and transmission.
These YVO4 and LiNbO3 birefringent wedges produce a large angular separation between orthogonally polarized beams in a very small space making them useful for telecom applications including WSS, isolators, interleavers, and more.
Birefringent Wedge Capabilities
Choose YVO4 or LiNbO3 , and specify size, wavelength, and anti-reflection coating options to meet your exact requirements.
