Self-assembled monolayers made using sub-micron dielectric spheres are analogous to atomic monolayers that have proved to be a modern workhorse in condensed matter physics. Here, we discuss the origin of optical resonances ...

We theoretically study the interaction between dual cavity modes in a planar photonic microcavity structure in the optical communication wavelength range. The merging and splitting of cavity mode is analysed with realistic ...

The interaction of polarized light with photonic crystals exhibits unique features due to its subwavelength nature on the surface and the periodic variation of refractive index in the depth of the crystals. Here, we present ...

We have studied angle- and polarization-dependent multiple Bragg diffraction in the high-energy region of a three-dimensional photonic crystal, which is quite distinctive as compared to the low-energy region. We ...

Optimizing scattering is the most sought-after goal in wave transport through photonic structures, which opens up many physical processes with prospective applications. Here, we uncover the appearance of a tunable frequency ...

The sparkling colors on the wing scales of butterflies are one of the most fascinating light–matter interactions in nature and have been an intense area of research in recent times. Controlling the light diffusion and ...

We discuss the symmetry-induced optical process in photonic crystals. The symmetry of crystal plays a vital role in the hybridization of stop gaps and the formation of photonic band gap.

We report experimental evidence of wavelength-dependent polarization anisotropy in 3D photonic crystals with fcc symmetry. We discuss the modification of Brewster angle due to involuted light scattering at the air-photonic ...
