The Polarization Beam Combiner/Splitter is a compact high performance lightwave component that combines two
orthogonal polarization signals into one output fiber. The most common application is to combine the light of two
pump lasers into one single fiber to double the pump power in EDFA or Raman Amplifier. The device can also be
used as a beam splitter.
