Journal ArticleDOI
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
Observation of PT-Symmetry Breaking in Complex Optical Potentials
A. Guo,Gregory J. Salamo,David Duchesne,Roberto Morandotti,M. Volatier-Ravat,Vincent Aimez,Georgios A. Siviloglou,Demetrios N. Christodoulides +7 more
TL;DR: This work demonstrates experimentally passive PT-symmetry breaking within the realm of optics, which leads to a loss induced optical transparency in specially designed pseudo-Hermitian guiding potentials.
Journal ArticleDOI
Observation of accelerating Airy beams.
TL;DR: In this paper, the first observation of Airy optical beams has been reported in both one-and two-dimensional configurations, and they exhibit unusual features such as the ability to remain diffraction-free over long distances while they tend to freely accelerate during propagation.
Journal ArticleDOI
Non-Hermitian physics and PT symmetry
Ramy El-Ganainy,Konstantinos G. Makris,Mercedeh Khajavikhan,Ziad H. Musslimani,Stefan Rotter,Demetrios N. Christodoulides +5 more
TL;DR: In this paper, the interplay between parity-time symmetry and non-Hermitian physics in optics, plasmonics and optomechanics has been explored both theoretically and experimentally.
Journal ArticleDOI
Parity–time synthetic photonic lattices
Alois Regensburger,Christoph Bersch,Mohammad-Ali Miri,Georgy Onishchukov,Demetrios N. Christodoulides,Ulf Peschel +5 more
TL;DR: The experimental observation of light transport in large-scale temporal lattices that are parity–time symmetric is reported and it is demonstrated that periodic structures respecting this symmetry can act as unidirectional invisible media when operated near their exceptional points.
