“…Even though three-dimensional Photonic Crystals (PCs), made of high index materials such as titanium dioxide 1 2 and silicon 3 , have been fabricated for instance by successive sputtering and electron beam patterning or from opal templates 4 5 6 , the infiltration of a lithographically structured polymer template appears to be a particularly effective strategy for obtaining large three dimensional PCs 7 8 and for embedding functional subunits for application in optical circuits or devices 9 10 11 . Tétreault et al reported the first silicon replica of such a woodpile template using the silicon double inversion technique 12 .…”

Photonic crystal materials are based on a periodic modulation of the dielectric constant on length scales comparable to the wavelength of light. These materials can exhibit photonic band gaps; frequency regions for which the propagation of electromagnetic radiation is forbidden due to the depletion of the density of states. In order to exhibit a full band gap, 3D PCs must present a threshold refractive index contrast that depends on the crystal structure. In the case of the so-called woodpile photonic crystals this threshold is comparably low, approximately 1.9 for the direct structure. Therefore direct or inverted woodpiles made of high refractive index materials like silicon, germanium or titanium dioxide are sought after. Here we show that, by combining multiphoton lithography and atomic layer deposition, we can achieve a direct inversion of polymer templates into TiO2 based photonic crystals. The obtained structures show remarkable optical properties in the near-infrared region with almost perfect specular reflectance, a transmission dip close to the detection limit and a Bragg length comparable to the lattice constant.

“…Lee et al [125] like many others, have probed the angle-resolved reflectance spectra of inverse opals. For TiO 2 IOs grown by repetitive vertical self-assembly and atomic layer deposition (ALD), they confirmed that the blue-shift of the stopband from the IO formed from the [111] planes of the parent opal follow the modified Bragg-Snell law:…”

This perspective reviews recent advances in inverse opal structures, how they have been developed, studied and applied as catalysts, catalyst support materials, as electrode materials for batteries, water splitting applications, solar-to-fuel conversion and electrochromics, and finally as photonic photocatalysts and photoelectrocatalysts. Throughout, we detail some of the salient optical characteristics that underpin recent results and form the basis for light-matter interactions that span electrochemical energy conversion systems as well as photocatalytic systems. Strategies for using 2D as well as 3D structures, ordered macroporous materials such as inverse opals are summarized and recent work on plasmonic–photonic coupling in metal nanoparticle-infiltrated wide band gap inverse opals for enhanced photoelectrochemistry are provided.

“…On the second topic related to crystals, two papers describe the optical properties of inverse opal structures and those of a wide bandgap chalcopyrite, respectively. Lee et al [8] describe titania inverse opal heterostructures demonstrating two distinctive photonic stopgaps fabricated by repetitive vertical self-assembly and atomic layer deposition (ALD). Angle resolved reflectance measurements of the inverse opal heterostructure are reported for the first time.…”
