Using the Maxwell-Bloch equations for resonantly absorbing and amplifying media, we
study the temporal dynamics of light propagation through the PT-symmetric structures with …

We theoretically demonstrate soliton steering in parity–time (PT)-symmetric coupled
nonlinear dimers. We show that if the length of the PT-symmetric system is set to 2π, contrary …

Parity-time (PT) symmetry is a fundamental concept in non-Hermitian physics that has
recently gained attention for its potential in engineering advanced electronic systems and …

The paper reports on the coupling of Parity-Time (PT)-symmetric whispering gallery
resonators with realistic material and gain/loss models. Response of the PT system is …

The present work investigates the switching dynamics of conventional fiber Bragg gratings
(FBGs) with saturable coupling and parity-time (PT)-symmetric fiber Bragg gratings …

We report the role of PT symmetry in switching characteristics of a highly nonlinear fiber
Bragg grating (FBG) with cubic-quintic-septimal nonlinearities. We demonstrate that the …

The central theme of this paper is the analysis of the usefulness of introducing four-wave
mixing or modulation of Kerr nonlinearity in a nonuniform grating structure with gain and …

The unique spectral behavior exhibited by a class of nonuniform Bragg periodic structures,
namely chirped and apodized fiber-Bragg gratings (FBGs) influenced by parity and time …

We study the PT-symmetric periodic layered structure with the modulated Kerr nonlinearity.
We demonstrate that such systems can be transformed from the full to the broken PT …

The interaction between forward and backward waves in a periodical structure with
$\mathcal {P}\mathcal {T} $-symmetric potential is investigated. The results demonstrate that …
