PM Splitter

PM Splitter is an optical device also known as Polarization Splitter. It is used to divide the input polarized light signal into two output channels, usually called the primary branch (major axis) and the secondary branch (minor axis).

The main function of PM Splitter is to distribute the input polarized light signal to the main branch and the secondary branch according to a certain beam splitting ratio, and to keep the polarization state of the optical signal consistent. The main branch and the sub-branch usually have different transmittances. The main branch has a higher transmittance and the sub-branch has a lower transmittance.

PM Splitter is usually composed of special optical devices, such as polarization gratings, fiber gratings or waveguide devices. These devices can split an optical signal into two different branches based on its polarization state while keeping the polarization direction of the optical signal unchanged.
