Paper Abstract

We prepared thin film colloidal crystals, namely, opals and Langmuir-Blodgett crystals, of different lattice constants and coated them with 20, 50 and 100 nm thick gold films. Angle-resolved transmission spectra of these hybrid nanostructures were obtained using linear polarized light over a spectral range of a photonic bandgap energy structure of these colloidal photonic crystals. Up to 10 times transmission enhancement has been observed in specific spectral intervals determined by the light coupling to surface plasmon polaritons in the metal film. At the same time these hybrid nanostructures retain transmission attenuation bands inherited from a photonic crystal. The strong crosscorrelation of the photonic bandgap and surface plasmon polariton properties was observed in the transmission spectra of studied hybrids.
