Model system for optical nonlinearities: Asymmetric quantum wells.
Emmanuel Rosencher,Ph. Bois +1 more
TL;DR: Large absorptions have been observed for the first time in GaAs/AlGaAs multiquantum wells (MQW) by West and Eglash by noting the dipole matrix elements associated to these intersubband transitions (ISBT) have the same order of magnitude as the quantum well width leading to extremely large absorption.
Journal ArticleDOI
Phase matching using an isotropic nonlinear optical material
TL;DR: In this paper, a quasi-phase matching scheme was proposed to compensate for optical dispersion, which results in different phase velocities for light of different frequencies in anisotropic birefringent crystals.
Journal ArticleDOI
Quantum Engineering of Optical Nonlinearities
TL;DR: The second-order optical nonlinearities in materials are of paramount importance for optical wavelength conversion techniques, which are the basis of new high-resolution spectroscopic tools as mentioned in this paper.
Book ChapterDOI
Intersubband transitions in quantum wells
TL;DR: In this article, the potential energy profile in semiconductor heterostructures can now be controlled in a fascinating way that could barely be dreamed of twenty years ago, and many devices have been designed according to this quantum engineering and have shown unsurpassed properties.
Journal ArticleDOI
Optical Transitions in Single-Wall Boron Nitride Nanotubes
Jean-Sébastien Lauret,Raul Arenal,François Ducastelle,A. Loiseau,M. Cau,Brigitte Attal-Trétout,Emmanuel Rosencher,Laurence Goux-Capes +7 more
TL;DR: Optical transitions in single-wall boron nitride nanotubes are investigated by means of optical absorption spectroscopy, and the nature of these lines is discussed, and two interpretations are proposed.
