首次报道了钇铁石榴石-钆镓石榴石（yigg - GGG）波导中具有静磁正向体积波的大带宽非共线共面磁光相互作用。采用单个微带换能器，在2200和3500 Oe的均匀直流磁场下，在1.317 μm波长处分别实现了0.78 GHz和1.03 GHz的中心带宽，TM0 - TE0模式转换效率分别为0.54%和0.50%。本文还对相关的耦合模分析进行了总结。
Very large bandwidth noncollinear coplanar magneto‐optic interaction with magnetostatic forward volume waves in an yttrium iron garnet‐gadolinium gallium garnet (YIG‐GGG) waveguide is reported for the first time. Bandwidths of 0.78 and 1.03 GHz centered, respectively, at the carrier frequencies of 2.5 and 6.0 GHz, and TM0 ‐TE0 mode‐conversion efficiencies of 0.54 and 0.50% have been achieved at the optical wavelength of 1.317 μm using a single microstrip transducer and homogeneous dc magnetic fields of 2200 and 3500 Oe. A summary of related coupled‐mode analysis is also presented.
