Meta-photonic Device~Possibility of Permeability Control in Semiconductor-based Photonic Device Combined with Metamaterial~

我们展示了结合超材料的基于inp的光学多模干涉仪（MMI）。MMI工作在1.5-μm光通信波长。该超材料由排列在MMI上的微小分裂环谐振器（SRRs）组成。在1.5 μm处，SRR超材料与光发生了共振，在该波长附近，超材料的相对磁导率增加到2.4。我们的研究结果显示了半导体光子器件与超材料结合的可行性。这将有助于开发新型光通信设备。

We demonstrated InP-based optical multi-mode interferometers (MMI) combined with metamaterials. The MMI operated at optical-communication wavelength, 1.5-μm. The metamaterial consisted of minute split-ring resonators (SRRs) arrayed on the MMI. Magnetic resonance established between the SRR metamaterial and light at 1.5 μm, and the relative permeability of the metamaterial increased to 2.4 around this wavelength. Our results show the feasibility of semiconductor-based photonic devices combined with metamaterials. This would be useful in the development of novel optical-communication devices.
