磁光（MO）开关利用动态施加的磁场来操作。本文提出的MO器件由在非晶硅-金刚石平台上制作的微谐振器（MRR）组成。开发了两种具有MRR的MO开关。在第一种类型中，开关状态由包括在器件中的外部磁场分量控制。通过MO和热光效应的组合，波长可调谐操作是可能的，而无需任何额外的加热器，并且宽带切换是可实现的。另一种类型的开关是一个自保持的光开关与FeCoB薄膜磁铁集成。开关状态由集成薄膜磁体的剩磁驱动，并且在没有任何电源的情况下保持该状态。关键词：光子集成电路，磁光，材料，微谐振器，光开关
Magneto-optical (MO) switches operate with a dynamically applied magnetic field. The MO devices presented in this paper consist of microring resonators (MRRs) fabricated on amorphous silicon-ongarnet platform. Two types of MO switches with MRRs were developed. In the first type, the switching state is controlled by an external magnetic field component included in the device. By combination of MO and thermo– optic effects, wavelength tunable operation is possible without any additional heater, and broadband switching is achievable. The other type of switch is a self-holding optical switch integrated with an FeCoB thin-film magnet. The switching state is driven by the remanence of the integrated thin-film magnet, and the state is maintained without any power supply. key words: photonic integrated circuits, magneto-optical, material, microring resonator, optical switch
