Abstract

A double wavelength infrared emission by plasmonic thermal emitter using stacked Au/SiO₂/Au/SiO₂/Au structure was investigated. The effective refractive index of sandwiched SiO₂ is higher than normal value due to the coupling of surface plasmons at the top and bottom Au/SiO ₂ interfaces. Two different localized surface plasmon modes were excited with the same metal width, but different SiO₂ layer thicknesses in top and bottom Au/SiO₂/Au tri-layer structures. The measured dispersion relation diagram and simulation demonstrated that the resonances were localized resonance and the distribution of magnetic field was concentrated at the central SiO₂ layer between two Au layers.
