This fiber-coupled Polarizing Beam Combiner / Splitter 2 ⇾ 2 is a compact opto-mechanical unit that splits the radiation guided in the two fiber cables in 2 output fiber cables, depending on the state of polarization, respectively with a high efficiency.

Optical Setup
The input ports are fiber-coupled to two SM fiber cables or to two PM fiber cables.
The radiation is split using a polarizing beam splitter cube and finally coupled again in two SM fiber cables or to two PM fiber cables.

Fiber Couplers
A fundamental component of a fiber-coupled Beam Splitters are the Laser Beam Couplers, which are the inputs into the opto-mechanical unit collimating the input radiation and, finally, couples the radiation back into the common polarization-maintaining fiber cable. The stability of the total Polarizing Beam Splitter is determined by the stability of the Laser Beam Coupler.
