Book Description
LA PREMIERE PARTIE: NOUS DECRIVONS LES EXPERIENCES QUE NOUS AVONS REALISEES POUR LA GENERATION D'IMPULSIONS COURTES (QUELQUES PICOSECONDES) A PARTIR DE RESEAUX DE DIODES (CHAPITRE II). LE REGIME DE BLOCAGE DE MODES EST OBTENU AUSSI BIEN EN CAVITE INTRINSEQUE QU'AVEC UNE CAVITE EXTERNE SPATIALEMENT SELECTIVE. DANS LE DERNIER CAS, IL EST POSSIBLE D'OBTENIR UN CONTROLE DE LA STRUCTURE DU CHAMP EMIS PAR LE RESEAU DE DIODES, LA LARGEUR DU FAISCEAU D'EMISSION CORRESPONDANT A LA LIMITE DE DIFFRACTION. LE MODELE NUMERIQUE ORIGINAL QUE NOUS AVONS DEVELOPPE EST ADAPTE A L'ANALYSE DE LA DYNAMIQUE (SUB)PICOSECONDE D'UN SYSTEME SEMICONDUCTEUR PLANAIRE AVEC UNE DESCRIPTION SIMULTANEE DES COMPORTEMENTS SPATIAUX ET SPECTRAUX EN DEUX DIMENSIONS. LE MODELE TIENT COMPTE DES INHOMOGENEITES SPATIALES 2-D, DE LA NON-LINEARITE DU GAIN, DE LA LARGEUR SPECTRALE FINIE DU GAIN, DE LA PRESENCE DE RESEAUX DE DIFFRACTION, ET DES VARIATIONS DE L'INDICE OPTIQUE AVEC LA CONCENTRATION DE PORTEURS. LA SECONDE PARTIE CONCERNE L'ETUDE EXPERIMENTALE DE FAISABILITE D'UN AMPLIFICATEUR OPTIQUE PLANAIRE EN OXYNITRURE DE SILICIUM (SION) DOPE EN ERBIUM ET YTTERBIUM SUR SUBSTRAT DE SILICIUM (CHAPITRE IV). LE DOPAGE A ETE EFFECTUE PAR IMPLANTATION IONIQUE A HAUTE ENERGIE (2-3 MEV). LES PREMIERS ESSAIS SUR DES GUIDES A RUBAN GRAVE NON-OPTIMISES ONT PERMIS DE COMPENSER LES PERTES D'ABSORPTION DES IONS ERBIUM ET D'ATTEINDRE LE NIVEAU DE TRANSPARENCE DU MATERIAU

Book Description
In this classic, David Bohm was the first to offer us his causal interpretation of the quantum theory. Causality and Chance in Modern Physics continues to make possible further insight into the meaning of the quantum theory and to suggest ways of extending the theory into new directions.

Book Description
The International Conference on Diffusion in Materials (DIMAT) is the benchmark conference series for diffusion in solids. DIMAT 2011 was organized by the University of Bourgogne in association with CNRS, Dijon (France). The conference showcased new results concerning theoretical tools as well as applied research approaches. Diffusion processes affect all types of materials: nanomaterials, materials for energy, metallurgy, glasses and ceramics, but each requires its own numerical tools.Volume is indexed by Thomson Reuters CPCI-S (WoS). This volume comprises most of the contributions presented at DIMAT 2011: 4 plenary lectures delivered by famous high-level scientists plus 88 contributions in the form of keynote lectures, talks and posters.
