Paper Abstract

We demonstrate a high-speed magneto-optic (MO) beam deflector baseo n iron garnet materials. In this design, the two films are dynamically activated by external magnetic fields to achieve the necessary phase shift to enable beam deflection. Using standard material parameters, a deflection efficiency of 20% is predicted at an operating frequency of 1.0 GHz. Diffraction effects and temporal response are discussed and illustated using a quasi-time-dependent beam propagation method. This theoretical framework is not only useful for the demonstration of the MO beam deflector, but it is also applicable in the design and optimization of other magneto-photonic devices.
