Coupled Magnetic Resonator Optical Waveguides - mimicking spin waves in coupled metamaterials

摘要

Optical resonators are important devices that control the properties of lightand manipulate light-matter interaction. Various optical resonators aredesigned and fabricated using different techniques. For example, in coupledresonator optical waveguides, light energy is transported to other resonatorsthrough near-field coupling. In recent years, magnetic optical resonators basedon LC resonance have been realized in several metallic microstructures. Suchdevices possess stronger local resonance and lower radiation loss compared withelectric optical resonators. This study provides an overall introduction on thelatest progress in coupled magnetic resonator optical waveguide (CMROW).Various waveguides composed of different magnetic resonators are presented andLagrangian formalism is used to describe the CMROW. Moreover, severalinteresting properties of CMROW, such as abnormal dispersions and slow lighteffects, are discussed and CMROW applications in nonlinear and quantum opticsare shown. Future novel nanophotonic devices can be developed using CMROW.
