Polarizing Beam Splitter Fiber

A beam splitter cube which may be polarizing or non polarizing.

Polarizing beam splitter fiber.

Thorlabs single mode fiber based polarization beam combiners pbc or splitters are designed to either combine two orthogonal polarizations into a single fiber or split a single input into its orthogonal linear polarizations through two fiber outputs. Overview newport s f pbc series polarization beam combiner splitters can be used to combine light from two pm input fibers into a single smf 28 output fiber or to separate the orthogonal polarization components of an input signal between two output fibers. Many beam splitters have the form of a cube where the beam separation occurs at an interface within the cube figure 2. For an ideal polarizing beamsplitter these would be fully polarized with orthogonal polarizations.

Beam splitting polarizers split the incident beam into two beams of differing linear polarization. In addition birefringent crystals and brewster windows are also offered for higher laser damage threshold requirements. Such glass polarizers perform best for short wavelength infrared light and are widely used in optical fiber communications. The devices on this page feature two legs of po.

Such a cube is often made of two triangular glass prisms which are glued together with some transparent resin or cement.
