Abstract

It is shown that the intensity of magneto-optical effects is enhanced by structures containing photonic crystal layers and an iron garnet ferromagnetic dielectric as they support the excitation of quasi-surface Tamm modes at the boundary between the two. Such structures have high Q-factor resonances and can enhance the transverse magneto-optical Kerr effect. Up to 100% magneto-optical modulation can be achieved due to near-surface localization of the electromagnetic field.

通过激发表面模态来控制光子晶体结构中辐射的磁光控制

摘要

结果表明，包含光子晶体层和铁石榴石铁磁电介质的结构增强了磁光效应的强度，因为它们支持在两者之间的边界处的准表面Tamm模的激发。这样的结构具有高Q因子共振，并且可以增强横向磁光Kerr效应。由于电磁场的近表面局部化，可以实现高达100％的磁光调制。
