Comme l’efficacit\u00e9 spectrale des fibres optiques semble avoir atteint sa limite, l’une des meilleures solutions consiste \u00e0 \u00e9tendre la largeur de bande spectrale des syst\u00e8mes optiques. Compte tenu de la demande de syst\u00e8mes d’amplification optique \u00e0 large bande passante, nous avons d\u00e9cid\u00e9 de mener des recherches sur les amplificateurs optiques \u00e0 semiconducteurs (SOA) car ils offrent un gain personnalis\u00e9 et une expansion flexible de la bande passante, avec une bonne int\u00e9grabilit\u00e9 et un faible co\u00fbt. Historiquement, les SOA rencontraient des limitations en termes de chiffre de bruit, de distorsions non lin\u00e9aires et de sensibilit\u00e9 \u00e0 la polarisation. Cependant, les r\u00e9cents progr\u00e8s en mati\u00e8re de conception ont montr\u00e9 des r\u00e9sultats prometteurs, positionnant les SOA comme des candidats viables pour les futures solutions de transmission optique. L’objectif de ma th\u00e8se est de d\u00e9velopper des SOA att\u00e9nuant ces inconv\u00e9nients, pr\u00e9sentant un faible chiffre de bruit et une puissance de sortie satur\u00e9e \u00e9lev\u00e9e, pour les rendre adapt\u00e9s \u00e0 une utilisation dans des r\u00e9seaux optiques \u00e0 large bande passante en multiplexage par r\u00e9partition en longueur d’onde (WDM). Dans ce travail, nous avons commenc\u00e9 par une br\u00e8ve introduction aux principes fondamentaux des SOA. Ensuite, je pr\u00e9sente nos conceptions standard, les r\u00e9sultats des mesures et des id\u00e9es d’am\u00e9lioration, accompagn\u00e9s d’un mod\u00e8le simple pour une optimisation ult\u00e9rieure. Ensuite, nous exposons quelques conceptions avanc\u00e9es et leurs excellents r\u00e9sultats. Enfin, l’application des SOA dans les syst\u00e8mes de transmission optique a \u00e9t\u00e9 explor\u00e9e, mettant en \u00e9vidence leur r\u00f4le dans les modules d’amplification en ligne. Cette recherche contribue \u00e0 faire progresser la compr\u00e9hension et l’application pratique des SOA dans les syst\u00e8mes de communication optique.<\/p>\n\n\n\n Abstract :<\/strong><\/p>\n\n\n\n The continuous increase in data transmission demands is compelling optical networks to evolve and enhance their transmission capacity. As the spectral efficiency of optical fibers seems to have reached its limit, one of the best solutions is to extend the spectral bandwidth of optical systems. Considering the demand for large-bandwidth optical amplification systems, we decided to research semiconductor optical amplifiers (SOA) as they offer customized gain and flexible bandwidth expansion, which has good integrability and low cost as well. Historically, SOA faced limitations in terms of noise figures, nonlinear distortions, and polarization sensitivity. However, recent advancements in design have shown promising results, positioning SOAs as viable candidates for future optical transmission solutions. The objective of my thesis is to develop SOAs that mitigate the drawbacks, having a low noise figure and high saturation output power, to make them suitable for using in wide-bandwidth wavelength division multiplexing (WDM) optical networks. In this work, we started with a quick introduction to SOA’s basic principles. Then, I demonstrate our three standard designs, measurement results, and improvement ideas, accompanied by a simple model for further optimization. After that, we show some advanced designs and their excellent results. In the end, the application of SOAs in optical transmission systems was explored, highlighting their role in in-line amplifier modules. This research contributes to advancing the understanding and practical application of SOAs in optical communication systems.<\/p>\n","protected":false},"excerpt":{"rendered":" L’Ecole doctorale :
