Spontaneous emission in one-dimensional photonic crystals

Physical Review E, 2005
We study the spontaneous emission of an atom embedded in a one-dimensional photonic crystal or superlattice using a classical electrodynamic theory of radiation. The rate of emission is a function of the frequency of the emitted photon, the dipole's position and orientation, as well as the geometric and material parameters of the superlattice.

Resonantly absorbing one-dimensional photonic crystals

Physical Review E, 2005
A compact theoretical description of the effects of dissipation on the propagation of light waves through a multilayer periodic mirror built from resonant absorbing atoms is presented. Depending on the lattice periodicity, ultranarrow photonic gaps, weak polaritonic gaps, as well as rather atypical gap structures may be observed.

Nanoparticle One‐Dimensional Photonic‐Crystal Dye Laser

Small, 2009
The stimulated emission from an organic dye adsorbed within the void network of a NP 1D (photonic crystals) PC, was studied. The nanoparticle one-dimensional photonic crystals (NP 1DPCs) were assembled by polyelectrolyte-assisted layer-by-layer deposition with subsequent calcination of the films to remove the polymer components. Each layer was prepared

One-Dimensional Photonic Crystal Waveguide

Integrated Photonics Research and Applications/Nanophotonics for Information Systems, 2005
Electromagnetic wave propagation in one-dimensional photonic crystal was examined. Slant incident wave couples to high order mode propagation of photonic bands on Brillouin zone boundary. The concept of one-dimensional photonic crystal waveguide was proposed.

Alcohol-Infiltrated One-Dimensional Photonic Crystals

2011
In this work, experimental results on the optical characterization of alcohol-infiltrated silicon/air one-dimensional photonic crystals (1D-PhCs), fabricated by electrochemical micromachining of silicon, are presented and compared with theoretical predictions. Infiltration of alcohols into 1D-PhCs produces reliable changes (redshift and increase of the

Ultrasmall demultiplexer by use of one-dimensional photonic crystal

Optics Letters, 2005
Silica-based one-dimensional photonic crystal (1D-PC) is fabricated by use of a high-spatial-frequency grating with input and output surfaces tilted with respect to its periodic direction. An incident beam is coupled with the first photonic band in the second Brillouin zone of the 1D-PC.

One-Dimensional Microwave Photonic Crystals

2019
Explores theoretical and experimental studies of the properties of one-dimensional photonic crystals. The authors also consider the possibilities of controlling the characteristics of microwave photonic crystals with the help of electric and magnetic fields and provide examples of new fields of application of microwave photonic crystals.

One-dimensional controllable photonic crystal

Journal of the Optical Society of America B, 2007
The nonlinear one-dimensional model of controllable photonic crystals is considered. A photonic crystal is formed in a dielectric film on which the electromagnetic pump and signal waves fall. It is shown that the shape of the superlattice is controlled by the variation of the external electrostatic field imposed on the film.

Resonances of a Finite One-Dimensional Photonic Crystal with a Defect

SIAM Journal on Applied Mathematics, 2013
This paper is concerned with the scattering resonances of a layered dielectric medium of finite extent. The photonic structure consists of a finite number of periodic layers and some defect embedded in the interior. It is proved that there exist resonances that are close to the point spectrum of an infinite layered structure.
