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 self-trapping of an optical beam due to the photorefractive effect.
Galen Duree,J. L. Shultz,Gregory J. Salamo,Mordechai Segev,Amnon Yariv,Bruno Crosignani,Paolo Di Porto,Edward J. Sharp,Ratnakar R. Neurgaonkar +8 more
TL;DR: In this article, a new type of spatial soliton has been predicted to be observable in a photorefractive crystal, where the interference between the beam's spatial-frequency components can be considered to write photore-fractive gratings on the crystal.
Journal ArticleDOI
Resonance fluorescence from a coherently driven semiconductor quantum dot in a cavity.
Andreas Muller,Edward B. Flagg,Pablo Bianucci,Xiaoyong Wang,Dennis G. Deppe,Wenquan Ma,J. Zhang,Gregory J. Salamo,Min Xiao,Chih-Kang Shih +9 more
TL;DR: It is shown that resonance fluorescence, i.e., the resonant emission of a coherently driven two-level system, can be realized with a semiconductor quantum dot and second-order correlation measurements further confirm nonclassical light emission.
Journal ArticleDOI
Resonantly driven coherent oscillations in a solid-state quantum emitter
Edward B. Flagg,Andreas Muller,John W. Robertson,Sebastien Founta,Dennis G. Deppe,Min Xiao,Wenquan Ma,Gregory J. Salamo,Chih-Kang Shih +8 more
TL;DR: In this paper, the Mollow triplet in the emission spectrum of a quantum dot was observed to be a readout modality for electron-spin states, which can be used for quantum key distribution or through post-selection to generate entangled photon pairs.
Journal ArticleDOI
Nonlinear refraction and absorption: mechanisms and magnitudes
Demetrios N. Christodoulides,Iam-Choon Khoo,Gregory J. Salamo,George I. Stegeman,Eric W. Van Stryland +4 more
TL;DR: In this article, the authors provide an in-depth treatment of the various mechanisms by which an incident light beam can produce an intensity- or flux-dependent change in the refractive index and absorption coefficient of different materials.
