Tamm plasmon-polaritons and Fabry-Perot excitation in a magnetophotonic structure

Abstract

A magnetophotonic Tamm structure with a bilayer film of Bi-substituted iron garnets (Bi:IG) with a significant magneto-optical (MO) response, placed in microcavity, and Tamm plasmon-polaritons (TPP) excited at the interface of the Au layer, were proposed. Optical and MO spectra of the hybrid state were investigated theoretically and experimentally in Faraday effect geometry at a normal incidence of the light wave. Anticrossing behavior of the TPP and Fabry-Perot resonances and dependence of spectral splitting on their hybrid state on the thickness of the Au layer was shown. By varying the thickness of the top SiO2 layer in the structure, the modifications of spectra on the TPP spectral position were described in detail. The results can be used to design tunable MO devices and sensors.

Purcell and Collection Efficiency Enhancement of Single NV‐ Center Emission Coupled to an Asymmetric Tamm Structure

“…The proposed structure contains multiple bilayers of dielectric (TiO 2 /SiO 2 ) material that can be fabricated by the sol-gel synthesis/sputtering techniques or an e-beam evaporation method. [23,24] The advantage of implementing this approach is that the emitter's position and tuning of resonance are possible by changing a few structural parameters. Besides, the proposed structure can be made over larger areas, such as on a one-inch Si wafer or quartz substrate.…”

“…In contrast, the Tamm structure can be fabricated using layer-by-layer deposition of dielectric material by sol-gel synthesis or an e-beam evaporation method. [23,24] The structure is characterized by a Tamm mode, which originates due to the total reflection induced by the DBR and the metal film. The Tamm mode is localized within the spacer layer, termed Tamm plasmon resonance (TPR).…”
