Available in PDF, EPUB and Kindle. Book excerpt: CE MEMOIRE TRAITE DE L'ETUDE DES PROPRIETES OPTIQUES LINEAIRES ET NON LINEAIRES (EFFETS POCKELS ET KERR) DE FILMS MINCES ORGANIQUES POLARISES DESTINES A LA MODULATION ELECTRO-OPTIQUE EN CONFIGURATION GUIDEE. CES FILMS SONT CONSTITUES D'UNE MATRICE POLYMERIQUE AMORPHE ET TRANSPARENTE DANS LE VISIBLE ET LE PROCHE INFRAROUGE. ON Y INCORPORE DES CHROMOPHORES POSSEDANT UN FORT MOMENT DIPOLAIRE PERMANENT AINSI QUE DE LARGES SUSCEPTIBILITES OPTIQUES MICROSCOPIQUES QUADRATIQUES ET CUBIQUES. ON PROFITE DU MOMENT DIPOLAIRE DES CHROMOPHORES POUR LES ORIENTER PERPENDICULAIREMENT AU PLAN DU FILM, PAR APPLICATION D'UN FORT CHAMP ELECTRIQUE STATIQUE. LA CENTROSYMETRIE EST AINSI ROMPUE, CONFERANT AU MATERIAU DES PROPRIETES ELECTRO-OPTIQUES. NOUS AVONS ETUDIE PLUSIEURS CATEGORIES DE FILMS DANS LESQUELS LES CHROMOPHORES SONT SOIT SIMPLEMENT DISSOUS, SOIT GREFFES CHIMIQUEMENT A LA MATRICE PAR PLUSIEURS TYPES DE LIAISONS CHIMIQUES. LE TYPE DE GREFFAGE DECIDE EN GRANDE PARTIE DE LA STABILITE TEMPORELLE DE LA STRUCTURE ORIENTEE. LE MATERIAU TEND EN EFFET A RETROUVER SA CENTROSYMMETRIE A CAUSE DE L'INTERACTION DIPOLAIRE. LES PROPRIETES OPTIQUES LINEAIRES ETUDIEES SONT LES INDICES COMPLEXES ET LEUR DISPERSION AINSI QUE LES PERTES PAR PROPAGATION. ON ETUDIE D'AUTRE PART LES NON-LINEARITES QUADRATIQUES PAR GENERATION DE SECOND HARMONIQUE. UNE CORRELATION EST ETABLIE ENTRE LES PROPRIETES LINEAIRES ET NON LINEAIRES D'UNE PART ET LES VARIATIONS DE LA BANDE D'ABSORPTION PRINCIPALE CONSECUTIVES A LA POLARISATION D'AUTRE PART. LES COEFFICIENTS ELECTRO-OPTIQUES SONT MESURES DIRECTEMENT A L'AIDE D'UNE TECHNIQUE NOUVELLE, BASEE SUR LA MODULATION DE LA REFLECTIVITE ELECTRIQUEMENT INDUITE SUR UN ECHANTILLON MULTICOUCHES DONT UNE EST LE POLYMERE ACTIF. LES RESULTATS SONT INTERPRETABLES SIMPLEMENT EN DEHORS DE LA BANDE D'ABSORPTION DU POLYMERE, MAIS L'ELABORATION D'UNE THEORIE RIGOUREUSE, BASEE SUR LA THEORIE DE LA REFLEXION SUR UN SYSTEME STRATIFIE ANISOTROPE EST NECESSAIRE DES QUE L'ABSORPTION DEVIENT IMPORTANTE. LE GRAND INTERET DE CETTE TECHNIQUE RESIDE DANS LA POSSIBILITE DE MESURER LES COEFFICIENTS ELECTRO-OPTIQUES QUADRATIQUES ET CUBIQUES DANS TOUTE LA BANDE D'ABSORPTION DU MATERIAU, CE QUI EST EN GENERAL IMPOSSIBLE AVEC LES TECHNIQUES MISES AU POINT PRECEDEMMENT. LA MESURE DE LA DISPERSION CHROMATIQUE DE CES COEFFICIENTS ET L'AJUSTEMENT A LA THEORIE PERMETTENT DE DETERMINER LA DIFFERENCE DE MOMENT DIPOLAIRE ENTRE L'ETAT DE BASE ET LE PREMIER ETAT EXCITE DU CHROMOPHORE. ON EN DEDUIT L'ORDRE DE GRANDEUR DE LA VALEUR HORS RESONANCE DE LA SUSCEPTIBILITE QUADRATIQUE POCKELS

Book excerpt: LES FILMS POLYMERES AMORPHES RENFERMANT DES ENTITES ACTIVES EN OPTIQUE NON LINEAIRE (ONL) POLARISEES SONT APPARUS COMME LES MATERIAUX LES PLUS PROMETTEURS POUR DES APPLICATIONS ELECTROOPTIQUES. CES SYSTEMES SOUFFRENT CEPENDANT D'UNE MAUVAISE STABILITE DE LEURS PROPRIETES ONL. JUSQU'A PRESENT, LES MEILLEURS RESULTATS EN TERMES D'EFFICACITE ET DE STABILITE ONT ETE OBTENUS EN FORMANT DES RESEAUX DE TYPE EPOXY-AMINE. SUIVANT CE SCHEMA, DEUX NOUVEAUX TYPES DE COMPOSES ACTIFS EN ONL TERMINES PAR DES FONCTIONS EPOXY ET UTILISANT DEUX TYPES D'ENTITES ONL ONT ETE SYNTHETISES. DES FILMS RETICULES/POLARISES ONT ETE ELABORES A PARTIR DE CES DIFFERENTS COMPOSES ET LEURS PROPRIETES ELECTROOPTIQUES ONT ETE TESTEES. DE FACON A DETERMINER UN PROTOCOLE DE POLARISATION/RETICULATION OPTIMAL POUR CHAQUE SYSTEME, LA RETICULATION A ETE SUIVIE A LA FOIE PAR MESURES DE TV ET SPECTROSCOPIE IR. UNE STABILITE A LONG TERME POUR DES TEMPERATURES ALLANT DE 80 A 130C A ETE DEMONTREE POUR CES SYSTEMES. UNE TV ELEVEE ASSOCIEE A LA FIXATION DES CHROMOPHORES PAR LEURS DEUX EXTREMITES APPARAISSENT COMME DES FACTEURS DETERMINANTS POUR LA STABILITE. LA NECESSITE D'UN PROTOCOLE DE CUISSON/POLARISATION COMPLEXE (CONDITIONS CRITIQUES D'OBTENTION D'UN PREPOLYMERE ET TEMPS DE CUISSON LONGS) REPRESENTE UN INCONVENIENT CERTAIN. UNE AUTRE APPROCHE BASEE SUR L'UTILISATION DE GROUPEMENTS PHOTORETICULABLES (CINNAMATE ET FURYLACRYLATE) A ETE SUIVIE. DANS CE CAS, DES REACTIONS PHOTOCHIMIQUES SE PRODUISENT ENTRE LES GROUPEMENTS PHOTORETICULABLES PORTES PAR UNE ENTITE ACTIVE EN ONL ET DES GROUPES DE MEME NATURE ATTACHES, VIA UN BRAS-ESPACEUR ALKYLE, SUR UNE CHAINE POLYMERE JOUANT LE ROLE DE MATRICE -HOTE.

Download or read book Applied Nonlinear Optics written by Frits Zernike and published by Courier Corporation. This book was released on 2006-01-01 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Directed toward physicists and engineers interested in the device applications enabled by nonlinear optics, this text is suitable for advanced undergraduates and graduate students. Its content is presented entirely on a classical basis and requires only an elementary knowledge of quantum mechanics. The authors demonstrate how real laboratory situations can diverge from ideal theory, acquainting readers with the kinds of problems common to construction of a nonlinear device. They also offer a detailed discussion of the practical problems and characteristics of nonlinear materials, as well as the selection procedures necessary to ensure the use of good material. Their treatment begins with an introduction to the theories of linear and nonlinear optics, along with the basic ideas behind them. Succeeding chapters explore phase matching and nonlinear materials, followed by detailed treatments of second-harmonic generation, parametric up-conversion, and optical parametric amplification and oscillation. Appendixes offer a comprehensive list of materials and their properties; the text concludes with references and an index.

Download or read book Photonic Crystals written by John D. Joannopoulos and published by Princeton University Press. This book was released on 2011-10-30 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since it was first published in 1995, Photonic Crystals has remained the definitive text for both undergraduates and researchers on photonic band-gap materials and their use in controlling the propagation of light. This newly expanded and revised edition covers the latest developments in the field, providing the most up-to-date, concise, and comprehensive book available on these novel materials and their applications. Starting from Maxwell's equations and Fourier analysis, the authors develop the theoretical tools of photonics using principles of linear algebra and symmetry, emphasizing analogies with traditional solid-state physics and quantum theory. They then investigate the unique phenomena that take place within photonic crystals at defect sites and surfaces, from one to three dimensions. This new edition includes entirely new chapters describing important hybrid structures that use band gaps or periodicity only in some directions: periodic waveguides, photonic-crystal slabs, and photonic-crystal fibers. The authors demonstrate how the capabilities of photonic crystals to localize light can be put to work in devices such as filters and splitters. A new appendix provides an overview of computational methods for electromagnetism. Existing chapters have been considerably updated and expanded to include many new three-dimensional photonic crystals, an extensive tutorial on device design using temporal coupled-mode theory, discussions of diffraction and refraction at crystal interfaces, and more. Richly illustrated and accessibly written, Photonic Crystals is an indispensable resource for students and researchers. Extensively revised and expanded Features improved graphics throughout Includes new chapters on photonic-crystal fibers and combined index-and band-gap-guiding Provides an introduction to coupled-mode theory as a powerful tool for device design Covers many new topics, including omnidirectional reflection, anomalous refraction and diffraction, computational photonics, and much more.

Download or read book Introduction to Glass Science and Technology written by James E Shelby and published by Royal Society of Chemistry. This book was released on 2015-11-06 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a concise and inexpensive introduction for an undergraduate course in glass science and technology. The level of the book has deliberately been maintained at the introductory level to avoid confusion of the student by inclusion of more advanced material, and is unique in that its text is limited to the amount suitable for a one term course for students in materials science, ceramics or inorganic chemistry. The contents cover the fundamental topics of importance in glass science and technology, including glass formation, crystallization, phase separation and structure of glasses. Additional chapters discuss the most important properties of glasses, including discussion of physical, optical, electrical, chemical and mechanical properties. A final chapter provides an introduction to a number of methods used to form technical glasses, including glass sheet, bottles, insulation fibre, optical fibres and other common commercial products. In addition, the book contains discussion of the effects of phase separation and crystallization on the properties of glasses, which is neglected in other texts. Although intended primarily as a textbook, Introduction to Glass Science and Technology will also be invaluable to the engineer or scientist who desires more knowledge regarding the formation, properties and production of glass.

This book was released on 2013-11-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.
