The Isolator Polarization Beam Combiner/Splitter is a compact device that provides both polarization beam combining and optical isolation in one integrated component. The most common application is to combine two pump lasers into one single fiber to double the pump power in EDFA or Raman Amplifier. The Beam Combiner/Splitter has extremely low insertion loss, and it can improve the amplifier performance.
The Dual Polarization Beam Combiner/Splitter, 2 × 2 PBC/PBS, is a compact high performance lightwave component that combines or divides two orthogonal polarization signals into one or two output fibers. The most common applications are in polarization mode dispersion compensator, EDFA, Raman Amplifier, coherent telecommunication systems and fiber sensor. The Dual Polarization Beam Combiner/Splitter is characterized with high extinction ratio and low insertion loss.
The Ultra Low Ratio Tap Coupler splits a very small amount of light from a signal path to a tap port. Low tap ratios such as 0.1%, 0.01% or 0.001% enable the monitoring photodetector to operate without damage or saturation. It is suitable for very high optical power, its main application is in the monitoring of optical sources such as fiber lasers.
The Polarization Maintaining Tap Coupler is manufactured by using advanced technology to allow the input signal to be split at various ratios with high extinction ratio.
