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.
