Recent progress on nonlinear properties of parity-time (PT)-symmetric systems is
comprehensively reviewed in this article. PT symmetry started out in non-Hermitian quantum …

One of the challenges of the modern photonics is to develop all‐optical devices enabling
increased speed and energy efficiency for transmitting and processing information on an …

The first good prediction of the multipole soliton solution for the non-integrable equation, ie,
the saturable nonlinear Schrödinger equation under the PT-symmetric potential, is achieved …

We report the realization of a coherent perfect absorber, using a pair of passive resonators
coupled to a microwave transmission line in the background, which can completely absorb …

We study spatial and temporal solitons in the PT symmetric coupler with gain in one
waveguide and loss in the other. Stability properties of the high-and low-frequency solitons …

We reveal a generic connection between the effect of time reversals and nonlinear wave
dynamics in systems with parity-time (PT) symmetry, considering a symmetric optical coupler …

In this paper, we provide a comprehensive review of unidirectional reflectionless light
propagation in photonic devices at exceptional points (EPs). EPs, which are branch point …

We report the existence and stability of lattice solitons in parity-time (PT)-symmetric mixed
linear-nonlinear optical lattices in Kerr media. We focus on studying the characteristic effects …

We introduce a one-dimensional parity-time-(PT-) symmetric nonlinear magnetic
metamaterial consisting of split-ring dimers having both gain and loss. When nonlinearity is …

We theoretically investigate the optical properties of parity-time (PT)-symmetric three-
dimensional metamaterials composed of strongly coupled planar plasmonic waveguides. By …
