1550nm ISO+Polarization Beam Combiner/Splitter

The 1550nm Isolator & 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.

Features

  • Low Insertion Loss
  • High Extinction Ratio
  • Compact In-Line Package
  • High Stability and Reliability

Applications

  • Polarization MUX/Demux
  • High power fiber laser
  • Optic sensor system
  • Coherent Telecommunication Systems
  • Polarization Mode Dispersion Compensator

The 1550nm Isolator & 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 IPBS/C. These devices can handle powers rang from 300mW to 10W or other on request, and have center operating wavelengths ranging from 1064 nm to 2050nm.

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 high power applications, we will use heat sink package, contact DK Photonics for details.
