Three-dimensional photonic crystals with an active surface: Gold film terminated opals

Hybrid Colloidal Plasmonic‐Photonic Crystals

“…Thus, the original idea behind investigation of the metal-on-opal hybrids was to build up a PhC with an active surface that is able to control the PhC properties over a broad spectral range. [ 93 ] The transmission spectrum of the Ag-opal hybrid ( Figure 21 ) deviates dramatically from that of the parent opal fi lm ( Figure 15 ) as well as from the spectra of the opal-Ag hybrid ( Figure 16 ). It is clearly dominated by the already discussed peak of the extraordinary transmission that is accompanied by SPP transmission passbands at oblique light incidence and transmission minima inherited from the PBG structure.…”

“…93. This effect can be understood by taking into account the light diffraction at different crystallographic planes in the side through the glass substrate, the refl ectance spectra look alike the spectra a bare opal, with a dominating peak at the (111) resonance, where light is diffracted by layers that are parallel to the sample surface.…”

“…The weaker transmission peak at 0.92 corresponds to the second EOT peak for the SPPs at the Au-air interface. [93] Its appearance does not contradict the onset of interband transitions, but it is suppressed by the absorption in a gold fi lm. Taking into account the possible normalization uncertainties, the remaining ratio difference is high enough to make a statement that the properties of a corrugated metal fi lm constitute a dominant factor for engineering the optical response of hybrid architectures.…”

Quasiguided modes of opaline photonic crystals covered by Ge2Sb2Te5

“…As it was demonstrated in Ref. 11, the presence of gold film terminating the opaline photonic crystal lattice leads to modification of angular transmission diagram owing to the coupling of the diffracted light to surface plasmon polaritons. In Refs.…”

Hybrid architectures: enabling 4-dimensional plasmonic-photonic crystals

“…The changes introduced to the light flow in the case of interfacing photonic and plasmonic crystals are much more dramatic. If 3D PhC is coupled to 2D PlC, the superposition principle remains the appropriate zero-order approximation for the interpretation of observed spectra 6 . In particular, one can distinguish four major resonance mechanisms participating in the light transport in 3D PhC-2D PlC hybrids -diffraction of photons at the dielectric lattice, diffraction of SPPs at the metal grating, scattering by localized plasmon resonance at metal semishells and the Fabry-Perot oscillations across the effective resonator formed by a hybrid slab.…”
