Air-core photonic band-gap fibers: the impact of surface modes

, 2004
We study the dispersion and leakage properties for the recently reported low-loss photonic band-gap fiber by Smith et al. [Nature 424, 657 (2003)]. We find that surface modes have a significant impact on both the dispersion and leakage properties of the ...

Huge local magnetic field enhancement at optical frequencies in metamaterials through coupling with photonic band gap

Results in Physics, 2019
We theoretically study the coupling of magnetic plasmon polaritons (MPPs) with photonic band gap (PBG) in a system composed of a one-dimensional (1D) silver nanowire pair array lying on a one-dimensional photonic crystal (1D PC).

Design and Analysis of a Novel Hexagonal Shaped Channel Drop Filter Based on Two-Dimensional Photonic Crystals [PDF]

Journal of Optoelectronical Nanostructures, 2016
In this paper a new optical channel drop filter (CDF) based on two dimensional (2-D) photonic crystals (PhC) with hexagonal shaped structure is proposed and numerically demonstrated by using the finite-difference-time-domain (FDTD) and plane-wave ...

Cavity quantum electrodynamics with three-dimensional photonic bandgap crystals

, 2015
This paper gives an overview of recent work on three-dimensional (3D) photonic crystals with a "full and complete" 3D photonic band gap. We review five main aspects: 1) spontaneous emission inhibition, 2) spatial localization of light within a tiny ...
