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 symmetry and exceptional points in photonics.
TL;DR: The role of PT symmetry and non-Hermitian dynamics for synthesizing and controlling the flow of light in optical structures is highlighted and a roadmap for future studies and potential applications is provided.
Journal ArticleDOI
Loss-induced suppression and revival of lasing.
Bo Peng,Sahin Kaya Ozdemir,Stefan Rotter,Huzeyfe Yilmaz,Matthias Liertzer,Faraz Monifi,Carl M. Bender,Franco Nori,Lan Yang +8 more
TL;DR: Overturning conventional wisdom that loss is bad and should be minimized, Peng et al. show that carefully tweaking the coupling strength between the various components of a coupled optical system can actually result in an enhancement of the optical properties by adding more loss into the system.
Journal ArticleDOI
Dynamically encircling an exceptional point for asymmetric mode switching
J. Doppler,Alexei A. Mailybaev,Julian Böhm,Ulrich Kuhl,Adrian Girschik,Florian Libisch,Thomas J. Milburn,Peter Rabl,Nimrod Moiseyev,Stefan Rotter +9 more
TL;DR: It is demonstrated that a dynamical encircling of an exceptional point is analogous to the scattering through a two-mode waveguide with suitably designed boundaries and losses, and mode transitions are induced that transform this device into a robust and asymmetric switch between different waveguide modes.
Journal ArticleDOI
Light fields in complex media: Mesoscopic scattering meets wave control
Stefan Rotter,Sylvain Gigan +1 more
TL;DR: In this article, a review summarizes how insights from mesoscopic scattering theory have direct relevance for optical wave control experiments and vice versa, and the results are expected to have an impact on a number of fields ranging from biomedical imaging to nanophotonics, quantum information, and communication technology.
