1550nm Polarization Beam Splitter (Port 3 as Single Mode Fiber)

1550nm Polarization Beam Splitter (Port 3 as Single Mode Fiber)

The Polarization Beam Splitter (PBS/PBC) is used to couple two orthogonal polarized light beams into a single optical fiber, or to couple the orthogonal polarized light from a single output into two separate optical fibers. It can also be used in reverse to couple two orthogonal polarized light beams from a polarization-maintaining fiber into a single-mode output fiber. These devices are commonly used for power combining in pump lasers, improving the power of fiber lasers. An important application of these devices is in polarization multiplexing and demultiplexing technology, which enhances the capacity of optical systems.
