Birefringence Crystal

For an optically anisotropic crystal, the refractive index varies linearly with the polarizability in the crystal. So, when the light passes through such crystals, the polarization of the exit light will be different than the polarization of the incident linght, and the birefringence phenomenon may occur.

Magneto-Optic LPE Garnet Faraday Rotator Crystals

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 as well as incorporated into a host of other non-reciprocal devices including circulators, switches and interleavers. Increasingly magneto-optic materials are also of interest for sensor applications.

All II-VI’s thick film Faraday rotators have been third-party certified to be in compliance with the European Union’s Restriction of Hazardous Substances (RoHS) directive.

II-VI’s low moment FLM Faraday rotator provides a good compromise between low temperature dependence and low saturation magnetization.

Our low loss FLL Faraday rotator is optimized to give low insertion loss across the telecommunications bands 1290-1610 nm (IL ≤ 0.05 dB @ 1550 nm, 0.02 dB typical) and offers other important design advantages.

Our low temperature dependence FLT Faraday rotator is designed to provide the lowest temperature dependence of the Faraday rotation angle in our product line for uncooled and wide band applications.

Our Latching MGL Faraday rotator enables the construction of devices without the use of a bias magnet, freeing the device designer from constraints of positioning, packaging materials, thermal mass and volume.

Micro Lenses

Micro Lenses in Photop refer particularly to C-Lens or D-Lens, which widely used for collimating or coupling beams after the fiber. With more than 10 years of experiences of lean production of Micro Lenses, Photop provide high volume C-Lens or D-Lens with different diameter from 1mm to 3mm.

Laser Coupling Lens

Spherical Lenses

A lens is a curved piece of ground and polished or molded material, usually glass, used for the refraction or focusing of light. Photop provides lenses a wide range of size and materials including BK7, Fused Silica, CaF2 and other glass types specified by customers. Similar to the cylindrical lens, spherical lenses are also widely used in the different applications, and Photop provides singlets, doublets and customized lenses assemblies.
