论文摘要
光学隔离器是光网络必不可少的组件。磁化隔离器具有出色的操作特性，包括低到没有功耗，但不适合在片上集成。介电常数的时间调制技术提供了一种无需磁场的隔离的替代方法，但并非没有自己的缺点。在这项工作中，我通过时间调节检查了光学隔离的多种方法，并表明是否通过载体注入，pockels和ocousto-optic效应或任何其他可能的可能方法来实现调制，基本上存在相同的对足迹，调制频率的约束，并且对于无需过分隔离而需要进行的功耗，并且最重要的是，最重要的是无需过多地隔离。据估计，这种功率至少达到一百毫米的顺序，并且该要求是否可以接受取决于磁极和时间调制的集成技术的持续进展。
Optical isolators are indispensable components of optical networks. Magneto-optic isolators have excellent operating characteristics, including low-to-no power consumption, but are not well suited for on-chip integration. The technique of temporal modulation of dielectric constant offers an alternative way to achieve isolation without magnetic field but is not without its own drawbacks. In this work I examine diverse methods of optical isolation via temporal modulation and show that independent on whether modulation is achieved by carrier injection, Pockels and acousto-optic effects, or any other conceivable method, there is essentially the same set of constraints on footprint, modulation frequency, and, most important, on power consumption required to achieve full isolation without excessive insertion loss. This power is estimated to be on the order of at least a hundred of milliwatts and whether this requirement is acceptable will depend on ongoing progress of both magneto-optic and time modulated integrated technologies.
