Analogies between electronic condensed matter systems and optics attract widespread
attention nowadays, underlying much research in photonics. Prominent examples where …

In this study, a novel, two-dimensional photonic crystal-based structure for the 2-to-4 optical
decoder is presented. The structure consists of 23 rows and 14 columns of chalcogenide …

In this paper, we investigate the acoustic flatbands (FBs) in phononic crystal (PnC) defect
lattices. The defects are introduced into a PnC composed of periodic rigid rods in the air …

In order to achieve the coloration and hydrophobicity of cotton fabrics through one-step
processing, this study utilized a vertical deposition method to fabricate polystyrene (PSt) …

A Si-based nanowire array photonic-crystal surface-emitting laser based on a flat band is
designed and simulated. By introducing an air gap between the nanowire and substrate, the …

A tight binding network of diamond shaped unit cells trapping a staggered magnetic flux
distribution is shown to exhibit a topological phase transition under a controlled variation of …

Abstract Spatially Variant Photonic Crystals (SVPCs) have shown the ability to control the
propagation and direction of light in the near-infrared spectrum. Using a novel approach for …

Inspired by complete graph theory, we demonstrate that a metallic claw “meta-atom”
structure can carry a high number of nearly degenerate resonant modes. A photonic …

We can generate the conditions for observing flat bands on initially trivial lattices by, for
example, exciting a given system simultaneously with different orthogonal states. In this …

Directional light manipulation plays an important role in the optical link and communication
of nanotechnology and modern optics. In this work, we provide a practical solution for …
