Ten years later, they have been independently and nearly simultaneously explored in the context of two antagonistic applications: one is concerned by broadband spread spectrum optical chaos communications and the other dealt with ultra high spectral purity microwave oscillations. We report here on recent surprising results obtained while developing nonlinear dynamical stability analysis for each application, and considering the relevant quantitative differences between the two configurations of the same oscillator architectures.","PeriodicalId":50779,"journal":{"name":"Annales De Physique","volume":"94 1","pages":"39-44"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89154108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A single photon collection efficiency of 17% is measured in a preliminary experiment performed on a single InAs QD located within a 250 nm diameter cylinder of GaAs. Because this photon collection strategy does not exploit the Purcell effect, it could also be efficiently applied to broadband single photon emitters such as F-centers in diamond.","PeriodicalId":50779,"journal":{"name":"Annales De Physique","volume":"398 1","pages":"151-154"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76460008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Elle stipule en particulier une description duale de la lumiere et de la matiere, presentant simultanement les proprietes d'une onde et d'une particule et conduisant ainsi a des representations classiques de la realite physique incompatibles. Le travail decrit dans cet ouvrage s'inscrit dans l'etude de la dualite onde-corpuscule pour un photon unique a l'aide d'une source de photons uniques fondee sur l'excitation impulsionnelle d'un centre colore NV individuel dans un nanocristal de diamant. Nous presentons dans un premier temps une experience d'interference a un photon tres proche dans sa conception de celle des trous d'Young. Cette experience nous permettra de discuter de la complementarite entre interference et connaissance du chemin suivi par la particule dans l'interferometre. Pour aller un peu plus au cœur des problemes conceptuels souleves par la dualite onde-corpuscule, nous decrivons par la suite la realisation experimentale de l'experience de pensee dite de “choix retarde” proposee par Wheeler au debut des annees soixante-dix. Dans cette experience, la decision de fermer ou non l'interferometre, et donc d'observer soit les interferences (associe a une propriete ondulatoire) soit le chemin suivi par le photon dans l'interferometre (associe a une propriete de type corpusculaire), n'est prise qu'une fois que le photon a franchi l'element separateur a l'entree de l'interferometre. Les resultats de cette experience nous permettront de conclure qu'aucune realite physique classique ne saurait etre attribuee au photon independamment de l'appareil de mesure, comme le stipule le principe de complementarite.","PeriodicalId":50779,"journal":{"name":"Annales De Physique","volume":"87 1","pages":"1-136"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82336823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
