Magneto-optic LPE garnet Faraday rotator crystals are used for non-reciprocal passive optical components such as isolators, circulators, switches, and interleavers.
All thick-film Faraday rotator materials from II-VI are RoHS-compliant.
Bismuth-doped rare-earth iron garnet thick films are the principal Faraday rotator materials for non-reciprocal passive optical devices in telecommunications applications. These garnet materials are highly transparent at the principal near-infrared telecommunications wavelengths. Combined with the correct polarizing or birefringent elements, these Faraday rotators can be made into polarization-dependent and -independent isolators.
