General Optics

C-Polarizer

Build circulators, data terminal equipment (DTE), data communications equipment (DCE), interleavers, and other optical datacom/telecom components with these optics.

Coherent C-polarizers combine a birefringent YVO4 beam displacer and a λ/2 waveplate to provide a compact, monolithic way of separating or combining polarization-multiplexed optical signals with high polarization purity in an epoxy-free optical path.

C-Polarizer Capabilities

Specify wavelengths, beam separations, polarization states, and dimensions to get the right C-polarizer for your specific application.
