Compact High Performance

General Details

Characteristics

  • Compact High Performance
  • High Extinction Ratio
  • Low Insertion Loss
  • High Directivity

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.
