980nm 1x2 Polarization Beam Splitter/ Combiner PBS/PBC

980nm 1x2 Polarization Beam Splitter/ Combiner PBS/PBC

Polarization beam splitters (PBS/PBC) are used to couple two orthogonal polarized light beams into one optical fiber or to couple a single output containing orthogonal linear polarized light beams into two optical fiber outputs. They can also be used in reverse to couple two orthogonal polarized light beams input from polarization-maintaining optical fiber branches into a single-mode output optical fiber. They can be used to combine the power of pump lasers and increase the power of fiber lasers. An important use of these two devices is to increase the capacity of optical systems in polarization multiplexing and demultiplexing technologies.
