Book excerpt: LE TRAVAIL DE CETTE THESE CONSISTE A ETUDIER THEORIQUEMENT ET EXPERIMENTALEMENT L'INFLUENCE DU BRUIT DE PHASE D'UN LASER A SEMI-CONDUCTEURS SUR LES PERFORMANCES ULTIMES DE SON ASSERVISSEMENT EN FREQUENCE SUR UNE RESONANCE OPTIQUE. TROIS REFERENCES SONT CHOISIES : UN INTERFEROMETRE DE MACH-ZENDER, UNE CAVITE FABRY-PEROT ET UNE VAPEUR ATOMIQUE. AFIN DE TESTER LES LIMITES DE CERTAINS MODELES USUELS DE DESCRIPTION DES FLUCTUATIONS DE PHASE DU LASER, J'UTILISE UNE THEORIE GENERALE IMPLIQUANT L'INTERFEROMETRE DE MACH-ZENDER ET BASEE SUR LE MODELE DU CHAMP LASER A DIFFUSION DE PHASE SANS RESTRICTION SUR LES VALEURS RELATIVES DES LARGEURS DE RAIES DU LASER ET DE LA REFERENCE. JE MONTRE QUE LE PROCESSUS DE MODULATION-DEMODULATION, EN PRESENCE DU BRUIT DE PHASE DU LASER, GENERE DEUX TYPES D'EXCES DE BRUIT PAR RAPPORT AU BRUIT DE GRENAILLE DE PHOTONS : BRUIT DE CONVERSION ET BRUIT D'INTERMODULATION. CES EXCES DE BRUIT S'AJOUTENT AU SIGNAL D'ERREUR ET LIMITENT LA STABILITE DU LASER ASSERVI. LES PREDICTIONS THEORIQUES CONFIRMEES PAR DES RESULTATS EXPERIMENTAUX MONTRENT QUE LA REPONSE FREQUENTIELLE D'UN SYSTEME ATOMIQUE A DEUX NIVEAUX EN REGIME DE FAIBLE SATURATION INTERROGE PAR UN CHAMP LASER BRUYANT EST IDENTIQUE A CELLE D'UNE CAVITE FABRY-PEROT ECLAIREE PAR LE MEME LASER. JE MONTRE QUE DANS LES CONDITIONS TYPIQUES D'ASSERVISSEMENT LA PURETE SPECTRALE DU LASER ASSERVI EST PRINCIPALEMENT LIMITEE PAR L'EXCES DE BRUIT D'INTERMODULATION. CET EFFET, INITIALEMENT MIS EN EVIDENCE DANS LE DOMAINE MICRO-ONDE, PEUT ETRE REDUIT AVEC UN CHOIX CONVENABLE DE LA CONFIGURATION DE DETECTION ET DE LA FREQUENCE DE MODULATION. AINSI UNE SOURCE LASER DE HAUTE PURETE SPECTRALE COMPATIBLE AVEC NOS APPLICATIONS PEUT ETRE REALISEE. LES RESULTATS DE CE MEMOIRE PEUVENT MENER A D'INTERESSANTES ETUDES SUR LES PHENOMENES DE BRUIT DANS LES DOMAINES DE LA METROLOGIE DES FREQUENCES, LA SPECTROSCOPIE A HAUTE RESOLUTION, LE REFROIDISSEMENT D'ATOMES PAR LASER ET LE POMPAGE OPTIQUE.

This book was released on 1989 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: We report our work on diode laser frequency stabilization emitting near 850 and 1300 nanometers.In first, we demonstrate a single-mode operation from an initially multimode diode laser with an optical feedback on an external mirror.Secondly, a confocal Fabry-Perot cavity is used to feedback the beam from the diode laser and provide resonant optical stabilization of the semiconductor laser. We present a detailed theoretical analysis of the static and dynamic frequency noise power spectrum of the coupled cavity laser field. Experimentally we achieve static frequency noise reduction of 50-60 dB and obtain a dramatic reduction of the laser line with from 20 MHz to a few kHz.The frequency tenability of these coupled cavity diode lasers are achieved by a double servo-loop system and we have obtained a continuously frequency tuning of 7 GHz without laser spectral purity degradation.Applications of these techniques include optical pumping Cesium docks and frequency synthesis in the visible.

Book excerpt: CE TRAVAIL PRESENTE DES RESULTATS EXPERIMENTAUX SUR LE ROLE DU COUPLAGE PHASE-AMPLITUDE ET DES MODES TRANSVERSES SUR LE BRUIT D'INTENSITE DES DIODES LASER. NOUS AVONS D'ABORD ETUDIE L'INFLUENCE DU COUPLAGE AMPLITUDE-PHASE SUR LE BRUIT D'UNE DIODE LASER DFB. L'AMPLITUDE ET LA PHASE DU CHAMP LASER DEPENDENT DU NOMBRE DE PORTEURS DANS LE MILIEU AMPLIFICATEUR ET SONT DE CE FAIT COUPLEES. LA CORRELATION DE LEURS FLUCTUATIONS PEUT ETRE UTILISEE POUR REDUIRE LE BRUIT D'INTENSITE A L'AIDE D'UN INTERFEROMETRE DE MICHELSON. C'EST CE QUE NOUS AVONS OBSERVE POUR DES COURANTS JUSTE AU-DESSUS DU SEUIL. POUR DES COURANTS PLUS ELEVES, LA CORRELATION TEND VERS ZERO. CES RESULTATS SONT TRES BIEN DECRITS PAR UN MODELE THEORIQUE. UNE GROSSE PARTIE DE CE TRAVAIL A CONSISTE EN L'ETUDE DE LA REPARATION SPATIALE DU BRUIT D'INTENSITE DANS UN FAISCEAU DE DIODE LASER MONOMODE. NOUS AVONS MIS EN EVIDENCE LA PRESENCE DE BRUIT DANS DES MODES SPATIAUX D'ORDRE SUPERIEUR. CES MODES D'ORDRES ELEVES SONT EN-DESSOUS DU SEUIL ET SEUL LE MODE TE 0 0 LASE.

LE PRINCIPE DE LA SUPPRESSION DU BRUIT DE POMPE EST UTILISE AVEC DIFFERENTES METHODES POUR REDUIRE LE BRUIT D'INTENSITE. LES LASERS SEMICONDUCTEUR A RUBAN ONT ETE ETUDIES EN UTILISANT DIFFERENTS TYPES DE TECHNIQUES D'AFFINEMENT SPECTRAL A TEMPERATURE AMBIANTE : DIODE SUR RESEAU ET INJECTION OPTIQUE. LA COMPRESSION DE BRUIT MESUREE EST DE 1.6 DB ET 2.3 DB RESPECTIVEMENT. LA PRINCIPALE CONCLUSION DE CETTE ETUDE EST QUE LE BRUIT D'INTENSITE DES DIODES LASER RESULTE DE L'ANNULATION ENTRE LES FLUCTUATIONS FORTEMENT ANTICORRELEES DU MODE PRINCIPAL ET DES FAIBLES ET NOMBREUX MODES LONGITUDINAUX. LES MESURES EFFECTUEES A BASSE TEMPERATURE MONTRENT L'IMPORTANCE DES CORRELATIONS QUANTIQUES ENTRE MODES DE POLARISATION ORTHOGONALE. L'ETAPE SUIVANTE EST L'ETUDE DES LASERS SEMICONDUCTEUR A MICROCAVITE (VCSELS). UNE COMPRESSION DE BRUIT DE 0.7 DB SOUS LE BRUIT QUANTIQUE STANDARD, RESULTANT DE FORTES ANTICORRELATIONS ENTRE LES MODES TRANSVERSES, A ETE OBSERVEE DANS UN VCSEL MULTIMODE.

Download or read book Corr lation du bruit de phase de lasers r seau de Bragg par injection optique written by Fabien Kéfélian and published by . This book was released on 2005 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le mélange de deux faisceaux laser sur un photo-détecteur permet de générer un signal radiofréquence jusqu'au THz. Par corrélation des deux sources optiques, le signal obtenu peut acquérir la pureté spectrale requise pour les réseaux de communications radio sur fibre. Notre travail porte sur la méthode de corrélation par accrochage optique sur un peigne de fréquences. L'injection optique permet de transférer le bruit de phase d'un laser maître, pris comme référence, à un laser esclave. En utilisant deux harmoniques d'un laser modulé en fréquence, comme sources distinctes d'injection, les bruits de phase des deux lasers esclaves sont corrélés et la différence de fréquences est multiple de la fréquence primaire. Nous avons réalisé une étude théorique générale de l'injection dans les lasers semi-conducteur à cavité complexe, en particulier les lasers DFB, en mettant notamment en évidence l'asymétrie géométrique du bruit. Nous avons relié théoriquement le degré de corrélation entre les deux lasers aux paramètres d'injection et au bruit de phase. L'expression a été confirmée par des mesures sur le contraste de franges d'interférences et le spectre du photo-courant hétérodyne. Ces battements temporels ont été mis en regard avec l'optique de Fourier et le speckle. Nous avons étudié la pureté spectrale du battement et établi les limites fondamentales de cette technique en fonction de la qualité de l'oscillateur primaire, des propriétés spectrales des lasers, des paramètres d'injection et de transport sur fibre. Les mesures de bruit de phase sur le signal généré expérimentalement, pour différentes conditions d'injection, sont en trés bon accord avec les expressions analytiques.

Available in PDF, EPUB and Kindle. Book excerpt: At the age of twenty-eight, Marty Ellis is still a bachelor who graduated with a major in journalism and a minor in photojournalism. He enjoys his life with various girlfriends while knocking back drinks in bars, going out to dinner, and rolling in the sheets. Yet inevitably, he grows tired of these surface-level-only feelings, shells out his standard goodbye speech, and moves on. However, using only his body and saying sayonara to his love lifeaEUR(tm)s revolving door is not how he wants to live for the rest of his life. How will he ever know what true love feels like if he doesnaEUR(tm)t ascertain how to actually give it? In what way will he begin to be able to discover the whole package that runs beneath the surface of a woman? Unexpectedly, Marty is blindsided when his best friend invites him to leave New Jersey for a weekend trip. Lauren Morris is a beautiful thirty-two-year-old woman who, after graduating at the age of twenty-one with a masteraEUR(tm)s degree in business, took a huge leap of faith and purchased an old farmhouse in Vermont. After ten years of hard work and sweat equity, she has transformed it into a beautiful inn that has become extremely lucrative. But winter is fast approaching, and she is dreading that feeling of loneliness that is connected to darkened afternoons and long, empty nights. Will a man ever enter her life? One that she could love and perhaps be with until death due them part? After meeting Marty, Lauren begins to consider if this man might be the one she has been waiting for her whole life. But then again, she is older than he is; long distance relationships hardly ever work out; and sudden heartbreaking unforeseen events rock both of their worlds. And if they do fall in love, which one of them will have to make the ultimate sacrifice and give up what theyaEUR(tm)ve worked so hard to achieve in order to be together? With so many changes causing so many challenges, will they get through them together, or will one push the other away?

Download or read book The Political Economy of Populism written by Petar Stankov and published by Routledge. This book was released on 2020-07-21 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Political Economy of Populism explores the interplay between identity, the economy and inequality to explain the dynamics of populist votes since the beginning of the 20th century. The book discusses the political and economic implications of populist governance using data on populist incumbencies and linking it to historical data on the macro economy and democracy. Chapters draw from the most recent political science, economics and other social science literature, as well as historical data, to explain the long-term causes and consequences of populism. Populism emerges and gains traction when political entrepreneurs exploit underlying identity conflicts for political gains. As the distributional consequences of both economic distress and economic growth typically favor the elite over the poor and the lower middle class, economic shocks usually sharpen the underlying identity conflicts between the groups. The book provides evidence of significant differences in the ways fiscal and monetary policies are conducted by incumbent populists in Latin America, Europe and the OECD. The work concludes by suggesting avenues through which a 21st century social consensus can be built, so that our society can avoid repeating the mistakes that led to wars and failed economic experiments in the 20th century. The Political Economy of Populism marks a significant contribution to the study of populism and is suited to students and scholars across the social sciences, including economics, political science and sociology.
