In this paper we introduce a method for creating a transparent computational boundary for the simulation of unidirectional propagation of optical beams and pulses using leaky modes. The key element of the method is the introduction of an artificial-index material outside a chosen computational domain and utilization of the quasi-normal modes associated with such artificial structure. The method is tested on the free space propagation of TE electromagnetic waves. By choosing the material to have…

A perfectly matched layer for the absorption of electromagnetic waves

TLDR
Numerical experiments and numerical comparisons show that the PML technique works better than the others in all cases; using it allows to obtain a higher accuracy in some problems and a release of computational requirements in some others.

Roundtrip matrix method for calculating the leaky resonant modes of open nanophotonic structures.

TLDR
The calculation of quasi-normal modes for two-dimensional photonic crystals where cavities are side- coupled and in-line-coupled to an infinite W1 waveguide is demonstrated, and it is shown that the scattering spectrum of these types of cavities can be reconstructed from the complex quasi- normal mode frequency.

Quasi-normal mode approach to the local-field problem in quantum optics

The local-field (LF) problem of a finite-size dipole emit- ter radiating inside a lossy inhomogeneous structure is a long-standing and challenging quantum optical problem, and it now is becoming more

Quasi-normal-modes description of transmission properties for photonic bandgap structures

We use the "quasi-normal-modes" (QNM) approach for discussing the transmission properties of double-side opened optical cavities: in particular, this approach is specified for one-dimensional (1D)

A 3D perfectly matched medium from modified maxwell's equations with stretched coordinates

TLDR
A modified set of Maxwell's equations is presented that includes complex coordinate stretching along the three Cartesian coordinates that allow the specification of absorbing boundaries with zero reflection at all angles of incidence and all frequencies.

Practitioner’s guide to laser pulse propagation models and simulation

TLDR
The modeling part of this guide concludes with a brief introduction into efficient implementations of nonlinear medium responses, and several worked-out simulation examples designed to highlight numerical and modeling issues, and to teach numerical-experiment practices.

Electromagnetic cavity modes in photonic and plasmonic resonators offer rich and attractive regimes for tailoring the properties of light–matter interactions, yet there is a disturbing lack of a

Compression of ultrashort laser pulses in planar hollow waveguides: a stability analysis.

TLDR
This geometry, the laser beam is guided with a fixed size in one transverse dimension, generating significant spectral broadening, while it propagates freely in the other, allowing for energy up-scalability, outperforms compression techniques based on hollow core fibers or filamentation.

Analytical description of quasi-normal mode in resonant plasmonic nano cavities

We propose an analytical model of quasi-normal mode (QNM) for resonant plasmonic nano cavities formed by sub wavelength grooves in metallic substrate. The QNM has shown great advantages in
