Our Faraday Rotator is bare magneto-optic crystal chip based on the Faraday magneto-optic effect. It produces non-reciprocal polarization rotation under an external magnetic field. As the core raw material for optical isolators, it is supplied to component manufacturers for secondary assembly.

Features

- Non-reciprocal polarization rotation

- Stable 45° rotation angle, custom rotation angle available

- Low insertion loss

- High isolation performance after assembling with polarizers and magnets

- Custom working wavelength supported

- Multiple shapes available: square (11×11mm as main specification) and round wafers

Application

Mainly used for manufacturing optical isolators, widely applied in laser systems and fiber optical communication systems.
