The top Ag film is perforated with parallel line-shape hole array. The induced AgSi O2 surface plasmons at both top and bottom AgSi O2 interface are found coupled together. The coupling effect results in the localized surface plasmon polaritons confined at the top AgSi O2 interface which exhibit the Fabry-Ṕrot resonance. The thermal emission peak position coincides with the reflection minimum in the dispersion relation and shifts to long wavelength as the Ag line width increases, which proves that the emission is due to the excitation of localized surface plasmon polaritons. Moreover, the emitted light is polarized perpendicular to the parallel metal lines. © 2008 American Institute of Physics. |
