Polarization Beam Splitter/Combiner, or PBS Fiber Polarization Beam Splitter, is a fiber assembly built on polarization-maintaining or regular fiber.  It is normally used for coupling two beams of ortho-polarized light into one fiber or coupling a single output containing ortho-linearly polarized light into two fiber outputs respectively. With its multi-functions, the polarization beam splitter is an important device in EDFA and Raman amplifiers.

As a manufacturer who is familiar with the polarization beam splitter principle and polarizing beam splitter theory, MEISU's PBS Polarization Beam Splitters are all featured with a wide operating wavelength with a specified center wavelength such as 1030/1064/1310/1480/1550. And other beams of special angular polarization states (e.g. 45°) can be coupled or separated with our products as well.

PBS/PBC Polarization Beam Splitter/Combiner Features

The PBS polarization beam splitter/combiner can be used to combine light from two PM input fibers into a single output fiber, or to separate the quadrature polarization components of the input signal into the two output fibers. Here are the features of MEISU high-power polarizing beam splitter/combiner:

Optical Path Epoxy Free

Wide operating wavelength

Low insertion loss

High return loss
High stability and reliability

IL<0.7db, er="">22dB
Custom design based on application

The idea for MUX/DEMUX and EDFA

Polarization Beam Splitter Principle

Polarization Beam Splitter /Combiner (PBS/PBC) normally work as a polarizing Beam Splitter, where a beam is divided into two orthogonal Polarization states. However, with the right use, the polarization beam splitter fiber can also work as a polarizing Beam combiner, where a polarized beam from two polarizable fibers combines a wave into a single-mode fiber for output.
