532nm Polarization Maintaining Beam Splitter

Our fused-fiber polarization beam combiners/splitters are used to couple two orthogonally polarized beams into a single fiber, or to split a single input beam into two orthogonal linearly polarized output beams. These devices operate entirely with fiber; polarization states are combined or separated at a fused-fiber junction. This all-fiber construction can achieve higher transmission rates and withstand higher powers than calcite prism-based polarization beam combiners. Since the polarization-maintaining fiber in a fused fiber polarizing beam combiner does not act as a polarizer, the input light must be linearly polarized and aligned with the fast and/or slow axis of the fiber. These devices are ideal for coupling light from two pump lasers into a single fiber to enhance the input light of an Erbium-doped or Raman fiber amplifier.
