Transparency in Bragg scattering and phase conjugation
TLDR
Reflectionless transmission of light waves with unitary transmittance is shown to occur in a certain class of gain-grating structures and phase-conjugation mirrors in the unstable regime of supersymmetric relativistic quantum mechanics.Abstract:
Reflectionless transmission of light waves with unitary transmittance is shown to occur in a certain class of gain-grating structures and phase-conjugation mirrors in the unstable (above-threshold) regime. Such structures are synthesized by means of the Darboux method developed in the context of supersymmetric relativistic quantum mechanics. Transparency is associated to superluminal pulse transmission.read more

Half-spectral unidirectional invisibility in non-Hermitian periodic optical structures
TL;DR: In this article, the authors introduced half-spectral unidirectional invisibility for one-dimensional periodic optical structures with tailored real and imaginary refractive index distributions in a non PT-symmetric configuration.

Bidirectional invisibility in Kramers-Kronig optical media.
TL;DR: A broad class of planar dielectric media with complex permittivity profiles that are fully invisible, for both left and right incidence sides, is introduced and the transition from unidirectional to bidirectional invisibility, and the possibility to realize sharp reflection above a cut-off incidence angle, are discussed.

Half-spectral unidirectional invisibility in non-Hermitian periodic optical structures

Unidirectional invisibility and enhanced reflection of short pulses in quasi-PT-symmetric media.
TL;DR: If the medium is quasi-parity-time (PT)-symmetric in the vicinity of the exceptional point, the propagation manifests strong unidirectional reflection and invisibility and due to strong frequency selectivity, quasi-PT-Symmetric periodic layers manifest efficient filtering of back-radiation.

The Inverse scattering transform fourier analysis for nonlinear problems
TL;DR: In this article, a systematic method is developed which allows one to identify certain important classes of evolution equations which can be solved by the method of inverse scattering, where the form of each evolution equation is characterized by the dispersion relation of its associated linearized version and an integro-differential operator.

On the synthesis of fiber Bragg gratings by layer peeling
TL;DR: It is found that the discrete layer-peeling algorithm is significantly faster and can be more stable than its continuous counterpart, whereas the continuous algorithm offers some advantages in flexibility.

Purely gain-coupled distributed feedback semiconductor lasers
TL;DR: In this paper, the authors proposed a new distributed feedback (DFB) laser structure in which almost pure gain coupling can be embodied in principle, without sacrificing low threshold operation, and an analysis of coupling coefficients has revealed the condition for canceling index-coupling component.
