Fourier-Imaging Spectroscopy of Two-Dimensional Gold Nanodisk Array on Photoluminescent Layer

In this paper, we theoretically and experimentally study the reflection and photoluminescence spectra angular dependencies of the two-dimensional gold nanodisk array on top of thin luminescent layer. Hydrogenated amorphous silicon-carbon alloy was used as a luminescent material with a high refractive index in the visible spectral range. Angle-resolved optical spectra were measured by a Fourier imaging spectroscopy in p- and s-polarizations. Both transverse electric (TE) and transverse magnetic (TM) quasiguided modes are clearly seen in the reflection and photoluminescence spectra in both polarizations simultaneously.
