我们实验研究了磁流体在集成硅光子学中的应用。利用铁流体包层硅微环谐振器，我们演示了通过外加磁场对谐振进行主动控制。尽管磁性纳米粒子引入了光学损耗，但仍获得了相对较高的负载质量因数6000。我们展示了在110Oe强磁场作用下的185 pm的共振位移，对应于包层MF的总折射率变化为-3.2×10(-3)。MFS和集成光子学的结合可能会导致磁可控光学设备和超紧凑、成本效益高的磁场传感器的发展。(C)2016年度美国光学学会
We experimentally investigate the application of magnetic fluids (MFs) on integrated silicon photonics. Using a ferro-fluid-clad silicon microring resonator, we demonstrate active control of resonances by applying an external magnetic field. Relatively high loaded quality factors on the order of 6000 are achieved, despite the optical losses introduced by the magnetic nanoparticles. We demonstrate resonance shifts of 185 pm in response to a 110 Oe strong magnetic field, corresponding to an overall refractive index change of -3.2 x 10(-3) for the cladding MF. The combination of MFs and integrated photonics could potentially lead to the development of magnetically controllable optical devices and ultra-compact cost-effective magnetic field sensors.
