Polarization Beam Combiner / Splitter
The Polarization Beam Combiner/Splitter-1310&1480&1550nm can be used either as a polarization beam combiner to combine light beams from two PM input fibers into a single output fiber, or as a polarization beam splitter to split light from an input fiber into two output fibers of orthogonal polarization states.
An important application of this device is polarization division multiplexing or demultiplexing in optical systems to increase their transmission capacity. In addition, as a pump combiner in optical amplifiers, the device efficiently combines the output from two pump lasers into a single fiber to increase the optical amplifier’s saturation power and to reduce its polarization sensitivity. The most common application is to combine the light of two pump lasers into a single fiber to double the pump power to an Erbium-Doped Fiber Amplifier (EDFA) or a Raman Amplifier.The wide operation bandwidth and high power handling capability (up to 5W) make the device very attractive for next-generation amplifier systems. Finally, with a rugged stainless package designed for high optical performance and stability, this compact device offers low excess insertion loss, low back reflection, and high extinction ratio that equal or surpass others on the market.
DK Photonics offers a large selection of PBS/C. These devices can handle powers rang from 300mW to 10W or other on request, and have center operating wavelengths ranging from 850 nm to 1650nm.
If you do not see a standard Polarization Beam Combiner/Splitter that meets your needs, we welcome the opportunity to review your desired specification and quote a custom Polarization Beam Combiner/Splitter.Requests for custom fiber pigtails, different wavelengths and handling power of operation or other specific needs will be readily addressed.
