Quantum well lasers -- Gain, spectra, dynamics
We discuss a number of theoretical and experimental issues in quantum well lasers with emphasis on the basic behavior of the gain, the field spectrum, and the modulation dynamics. It is revealed that the use of quantum well structures results in improvement of these properties and brings several new concepts to optical semiconductor devices

Crystal structure of (E)-1-{[(3,5-dimethylphenyl)imino]methyl}naphthalen-2-ol
This is an open-access article distributed under the terms of the Creative Commons Attribution Licence.The title compound, C19H17NO, has an E conformation about the N=C bond. The molecule is relatively planar, with the benzene ring and naphthalene ring plane being inclined to one another by 4.28 (10)°. There is an intramolecular O—H⋯N hydrogen bond generating an S(6) ring motif. In the crystal, molecules are linked via C—H⋯O hydrogen bonds, forming chains propagating along [100]. Within the chains there are π–π interactions involving the benzene ring and the naphthalene ring system of an adjacent molecule [inter-centroid distance = 3.6405 (14) Å].We thank the Spanish Ministerio de Economía y Competitividad (MAT2013-40950-R and FPI grants: BES-2011-046948 to author MSMA) and the ERDF for financial support.Peer Reviewe
