Over the last three decades, colloidal crystallization has provided an easy-to-craft platform
for mesoscale engineering of photonic and phononic crystals. Nevertheless, the crystal …

The daytime radiative coolers offer a sustainable way to passively cool objects under direct
sun exposure with the merits of zero energy consumption and zero pollutant generation …

We study theoretically the band-gap structures of several types of three-dimensional
photonic crystals with the fcc lattice symmetry: synthetic opals, inverted yablonovite and …

Coupling of polarized light to thin silica-air opal films—representatives of high contrast three-
dimensional photonic crystals—has been studied in detail. Photonic stop bands were …

We present a study of a Fano resonance between a narrow Bragg band and disorder-
induced continuum in photonic crystals where the continuum is either of the broad band …

Nonlinear diffraction in three-dimensional silicon-filled photonic crystals of opals is studied.
Efficient backward second-harmonic generation (SHG) is observed in the specular direction …

We report on a comprehensive experimental and theoretical study of light diffraction from
synthetic opals. A general theory of coherent elastic scattering (Bragg diffraction) is …

We studied polarization-and angle-resolved optical transmissivity of high quality synthetic
opals and found a strong anisotropy in the intensity of the transmitted light at different …

Polarization characteristics of light interaction with the photonic crystal of a-SiO2 synthetic
opals were studied under the conditions of low dielectric contrast. We analyzed 3D …

We demonstrate that, in contrast with the well-studied photonic crystals consisting of two
homogeneous components, photonic crystals comprised of inhomogeneous or multiple …
