Abstract
Infrared spatial modulation spectroscopy enables one to acquire background-free spectra of subwavelength sized objects. With this method we have investigated thermally excited single and double metal-insulator-metal plasmonic antennas (MIMs). On single MIMs with silica insulator, the same resonance condition is satisfied at different wavelengths due to the strong dispersion of silica. On double MIMs, the thermal radiation spectra bear the signature of hybridized electromagnetic modes which are simultaneously excited when the gap separation between the antennas is in the 100 nm range.
