Project Description

980nm Polarization Beam Combiner/Splitter

The 980nm Polarization Beam Combiner/Splitter 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.

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.

  1. above specifications are for device without connector. All parameters are tested at room temperature.
  2. For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower and ER will be 2dB lower. The default connector key is aligned to slow axis. Power transmits through the connector less than 2W.
  3. For >10W high power applications, we will use heat sink package, contact DK Photonics for details.
  4. Since the light is bidirectionally reversible, PBC can also be used as PBS.

Package Dimension

*Due to ongoing design improvements, the package size is subject to change. Please contact DK Photonics for confirmation.

Order information  P/N: PBC/PBS-①-②-③-④-⑤-⑥-⑦

When you inquire, please provide the correct P/N number according to our ordering information, and attach the appropriate description would be better. If need any connector, we do not recommend choosing a 250μm bare fiber pigtail.
