Faraday Rotators

Faraday rotator provides non-reciprocal rotation while maintaining linear polarization. The plane of polarization will be rotated 45°when light transmits through the Faraday rotator in the forward direction and rotated additional 45°in the same relative direction with respect to magnetic field when light travels backwards from the reverse direction. It will effectively reject the light traveling backward.

    CASTECH is dedicated to grow magneto-optical crystals with high Verdet constant and low absorption coefficient  to ensure higher level reliability and less degradation. Combined with our unique high LIDT process technology, we are able to supply customized Faraday rotators for high power applications, up to 500W average power. The working wavelength of our Faraday rotator family ranges from 355nm to 4500nm.
