TLDR
It is shown that new types of nonlinear self-trapped modes can exist in optical PT synthetic lattices.Abstract:
We investigate the effect of nonlinearity in novel parity-time (PT) symmetric potentials. We show that new types of nonlinear self-trapped modes can exist in optical PT synthetic lattices.read more

Observation of parity–time symmetry in optics
Christian E. Rüter,Konstantinos G. Makris,Ramy El-Ganainy,Demetrios N. Christodoulides,Mordechai Segev,Detlef Kip +5 more
TL;DR: In this paper, the authors report the first observation of the behaviour of a PT optical coupled system that judiciously involves a complex index potential, and observe both spontaneous PT symmetry breaking and power oscillations violating left-right symmetry.
Journal ArticleDOI
Exceptional points in optics and photonics.
TL;DR: The topic of exceptional points in photonics is reviewed and some of the possible exotic behavior that might be expected from engineering such systems are explored, as well as new angle of utilizing gain and loss as new degrees of freedom, in stark contrast with the traditional approach of avoiding these elements.

Experimental demonstration of a unidirectional reflectionless parity-time metamaterial at optical frequencies
Liang Feng,Ye-Long Xu,William S. Fegadolli,William S. Fegadolli,Ming-Hui Lu,José Edimar Barbosa Oliveira,Vilson R. Almeida,Yan-Feng Chen,Axel Scherer +8 more
TL;DR: The demonstrated unidirectional phenomenon at the corresponding parity-time exceptional point on-a-chip confirms the feasibility of creating complicated on-chip parity- time metamaterials and optical devices based on their properties.

Topologically protected bound states in photonic parity–time-symmetric crystals
Steffen Weimann,Mark Kremer,Yonatan Plotnik,Yaakov Lumer,Stefan Nolte,Konstantinos G. Makris,Mordechai Segev,Mikael C. Rechtsman,Alexander Szameit +8 more
TL;DR: This work shows theoretically and experimentally the existence of states that are localized at the interface between two topologically distinct PT-symmetric photonic lattices, and finds analytical closed form solutions of topological PT-Symmetric interface states.
Journal ArticleDOI
Optical spatial solitons: historical overview and recent advances
TL;DR: A brief overview of optical spatial solitons is provided, which will cover a variety of issues pertaining to self-trapped waves supported by different types of nonlinearities, as well as various families of spatialsolitons such as optical lattice soliton and surface solitONS.
