“…Band tuning in three-dimensional photonic crystals via the ambient temperature was first demonstrated in liquid crystal materials [62,77,78]. Large band shifts were also shown in opals filled with a suitable material exhibiting a phase transition in a convenient temperature range.…”

“…The spectral width of the PSB is dependent on refractive index contrast and can be changed by filling the voids of opal with suitable substances [60]. Modern technology allows to fill opal voids with various dielectrics [61], semiconductors [38,60], liquid crystals [62], and metals [63]. As an example, Fig.…”

“…[172] Conducting polymers have a great interest and can be synthesized in the preformed opals by electro- [173] or other polymerization, and can show electrical conductivity and luminescent properties. [174] If the eletropolymerization is performed on a thick sedimented opal, the thickness of the final infiltrated opal can be controlled by the reaction time.…”

Photonics, the technology of photons (as electronics is the technology of electrons), promises to be the new century's driving force in the advancement of, mainly but not only, information technology, such as communications and computing. This technology was initiated with the advent of lasers and optical fibers that, for various reasons, embody the best choice of source and channel of the information carrier: the photon. If the parallel with electronics is to be further pursued, one soon realizes that many more components are needed not only in the transport section of the technology but also, and principally, in the logic section: signal processing. An answer is promised to many of these demands by the potentiality of the new photonics era: photonic bandgap (PBG) materials, otherwise known as photonic crystals (PCs). In the present review a general perspective is presented on the state of the art in PC technology providing a broad audience‐oriented description of fundamentals and properties.

“…It has been demonstrated that anions in an electrolyte can be electrochemically doped into conducting polymers such as polyaniline and polythiophene, which can cause a change in the refractive index of the polymer. [12,13] As a result, the optical stopband of silica opals can be finely tuned by electrochemical doping of anions into the conducting polymer matrix infiltrated into the opals. [12] In the present paper, we employ an elegant nanochemical technique to demonstrate the fabrication of polyaniline (PANI), a conducting polymer, inverse opals by templating ordered colloidal assemblies.…”
