TL;DR: Reflectance measurements reveal the existence of multiple resonance modes of the nanorod metamaterials, and numerical simulations show that the electric field at the longitudinal resonances forms standing waves in the nanocavities due to the near-field coupling between the adjacent nanorods, and a new hybrid mode emerges due to a coupling between Nanorods and a gold-film substrate.

TL;DR: In this article, the physics and realisation of topological photonics on small scales, with the dimensions often smaller or comparable with the wavelength of light, are discussed, and a novel photonic platform employing higher-order topological effects for creating subwavelength highly efficient topologically protected optical cavities.

TL;DR: In this article, a position-sensitive generalized Lorentzian formalism for the decay of an excited atom in photonic crystals is derived, and an exact numerical method for calculating the local coupling strength, proportional to the photonic local density of state (LDOS), is presented.

TL;DR: In this paper, the existence of surface gap modes, known as Tamm states for electronic systems, in truncated photonic crystals formed by two types of dielectric rods was predicted.

TL;DR: In this article, the authors studied the effect of adding a lossless dielectric layer to a double-layer waveguide with the property of parity-time symmetry and showed that the added layer can control a ratio of gain and loss required to support propagating and non-decaying optical guided modes.
