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

我们展示了基于InP的光学多模干涉仪（MMI）与超材料相结合。MMI工作波长为1.5 μm。超材料由排列在MMI上的微小开口环谐振器（SRR）组成。在1.5 μm处，SRR超材料与光之间建立了磁共振，并且超材料的相对磁导率在该波长附近增加到2.4。我们的研究结果表明，基于光子晶体器件结合超材料的可行性。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.
