Design and characterization of a ferromagnetic, air gapped magneto-optic Faraday rotator.
Additional Document Info
A method has been developed to modulate the plane of polarized light through the use of a high permeability ferrite core design. A proof-of-principal, optical Faraday effect device has been constructed and tested. Magnetic fields were generated to provide up to 1deg of rotation at frequencies of direct current up to 10kHz using a terbium gallium garnet crystal rod.
