“…The dynamic shift of the PSB induced by the action of the optical nonlinearity was first analyzed by Scalora and co-workers in one-dimensional photonic crystals [25], the theory was extended for the case of two [88] and three dimensions [89,90]. The first optically induced switching in a 3D photonic crystal was observed in crystalline colloidal arrays of dyed poly-spheres on the nanosecond timescale [91].…”

The paper reviews computational models for plasmonic field enhancement, especially with applications to tip-enhanced scanning near-field optical microscopy (SNOM). Both plasmon-enhanced and scattering-type SNOM are considered. The importance of full electrodynamic analysis is emphasized: the electrostatic treatment is valid only if the size of the whole system, rather than its individual components (such as the apex of the tip or an individual particle in a cluster), is much smaller than the wavelength. Illustrative numerical results are included.Keywords near-field enhancement · plasmonic resonances · scanning near-field optical microscopy (SNOM) · tip-enhanced microscopy · superfocusing · electrodynamic analysis · computer simulation · the finite element method · the finite difference method · flexible local approximation methods

“…Complete dynamic control over the photonic density of states is only possible in 3D photonic structures. 23,24 Optically induced switching on a nanosecond timescale in a 3D photonic crystal was observed in crystalline colloidal arrays of dyed polyspheres. 25 Later, ultrafast picosecond switching in 3D photonic crystals was shown both in opals filled with carbon nanotubes 26 and in an array of ordered polystyrene spheres.…”

Ultrafast Bragg switching induced by a phase transition in a 3D photonic crystal

We demonstrate ultrafast shifting of a photonic stop band driven by a photoinduced phase transition in vanadium dioxide (VO 2 ) forming a three-dimensional photonic crystal. An ultrashort 120-fs laser pulse induces a phase transition in VO 2 filling the pores of an artificial silica opal, thus changing the effective dielectric constant of the opal. Consequently, the spectral position of the photonic stop band blue-shifts producing large changes in the reflectivity. The observed switching of the photonic crystal is faster that 350 fs. The demonstrated properties of opal-VO 2 composite are relevant for potential applications in all-optical switches, optical memories, low-threshold lasers, and optical computers.
