Description

the Polarization Beam Combiner & Splitter is a device with compact size , which combines two orthogonal polarization signals into one output fiber. PBC/PBS is commonly applied to combining the reflected light of fiber laser with fixed phase difference to one fiber ,to receive the interferometric fringe in Fiber Optics Current Transducer(Foct), Gyro, Raman Amplifier,with high extinction ratio. PBC/PBS can also be used as a PM splitter.
