Journal ArticleDOI
Ultrafast pulse interactions with two-level atoms
TL;DR: In this paper, an iterative predictor-corrector finite-difference time-domain method is used to solve the semiclassical Maxwell-Bloch system numerically without invoking any of the standard approximations such as the rotating-wave approximation.
Journal ArticleDOI
Optical discrete solitons in waveguide arrays. 2. Dynamic properties
Ulf Peschel,Roberto Morandotti,John M. Arnold,J. Stewart Aitchison,Hagai S. Eisenberg,Yaron Silberberg,Thomas Pertsch,Falk Lederer +7 more
TL;DR: In this paper, an AlGaAs waveguide array below the half-bandgap is used to investigate experimentally basic dynamic features of discrete systems and nonlinear locking of a discrete soliton to its input waveguide was observed for certain input conditions.
Journal ArticleDOI
Optical discrete solitons in waveguide arrays. I. Soliton formation
Hagai S. Eisenberg,Roberto Morandotti,Yaron Silberberg,John M. Arnold,Giovanni Pennelli,J.S. Aitchison +5 more
TL;DR: In this article, the authors investigate the generation of discrete spatial solitons in arrays of coupled waveguides, where light was launched into the center of the array, and different beam sizes and array geometries were tested.
Journal ArticleDOI
An all-optical switch employing the cascaded second-order nonlinear effect
TL;DR: In this paper, a cascaded second-order nonlinear switch based on a Mach-Zehnder interferometer with quasi-phase matching has been proposed, which can switch with power around 1.3 W in a length of approximately 1 cm.
Journal ArticleDOI
Quasi phase matching in GaAs--AlAs superlattice waveguides through bandgap tuning by use of quantum-well intermixing.
A. Saher Helmy,David C. Hutchings,T.C. Kleckner,John H. Marsh,A.C. Bryce,John M. Arnold,Colin Stanley,J.S. Aitchison,Christian T. A. Brown,Konstantinos Moutzouris,Majid Ebrahim-Zadeh +10 more
TL;DR: The observation of second-harmonic generation by type I quasi phase matching in a GaAs-AlAs superlattice waveguide is reported, which demonstrated narrowing owing to the finite bandwidth of the quasi-phase-matching grating.
