Cela a conduit \u00e0 l’exploration de nouvelles technologies favorisant une densit\u00e9 plus \u00e9lev\u00e9e et une efficacit\u00e9 \u00e9nerg\u00e9tique optimis\u00e9e. Parmi ces technologies, les circuits int\u00e9gr\u00e9s photoniques (PIC, pour Photonic Integrated Circuits) sur une plateforme h\u00e9t\u00e9rog\u00e8ne III-V sur silicium (SOI, pour Silicon-On-Insulator) se distinguent par leur potentiel d’int\u00e9gration de divers composants, tout en maintenant des co\u00fbts de production comp\u00e9titifs et en r\u00e9duisant la consommation \u00e9nerg\u00e9tique des futurs \u00e9metteurs. L\u2019int\u00e9gration de mat\u00e9riaux III-V par collage mol\u00e9culaire sur plaque de silicium permet de b\u00e9n\u00e9ficier d’un gain optique sur puce gr\u00e2ce \u00e0 l’utilisation de ces mat\u00e9riaux, tout en tirant parti de la densit\u00e9 \u00e9lev\u00e9e et de la maturit\u00e9 des fonderies CMOS. Dans cette th\u00e8se, j\u2019ai men\u00e9 une \u00e9tude th\u00e9orique et exp\u00e9rimentale sur les lasers \u00e0 r\u00e9troaction distribu\u00e9e (DFB) modul\u00e9s directement. En exploitant les propri\u00e9t\u00e9s de cette plateforme, nous avons int\u00e9gr\u00e9 un modulateur par \u00e9lectroabsorption (MEA) avec ces DFB pour \u00e9tudier la modulation externe. Pour att\u00e9nuer les pertes de puissance optique induites par le modulateur, nous avons int\u00e9gr\u00e9 un amplificateur optique \u00e0 semiconducteurs (SOA). Une \u00e9tude similaire a \u00e9t\u00e9 men\u00e9e pour un laser accordable, \u00e9galement modul\u00e9 de mani\u00e8re externe avec un MEA, co-int\u00e9gr\u00e9 avec un SOA.<\/p>\n\n\n\n Given the increasing bandwidth demands of optical communication systems, which must support constantly rising data traffic, along with a heightened awareness of sustainability issues, it becomes crucial to design devices that consume less energy. This has led to the exploration of new technologies that promote higher density and optimized energy efficiency. Among these technologies, photonic integrated circuits (PICs) on a heterogeneous III-V-on-SOI (Silicon-On-Insulator) platform stand out for their potential to integrate various components while maintaining competitive production costs and reducing the energy consumption of future emitters. The integration of III-V materials through molecular bonding onto silicon wafers allows for an optical gain on-chip due to the use of these materials, while leveraging the high density and maturity of CMOS foundries. In this thesis, I conducted a theoretical and experimental study on directly modulated distributed feedback (DFB) lasers. By exploiting the properties of this platform, we integrated an electro-absorption modulator (EAM) with these DFB lasers to investigate external modulation. To mitigate the optical power losses induced by the modulator, we integrated a semiconductor optical amplifier (SOA). A similar study was conducted for a tunable laser, also externally modulated with an EAM, co-integrated with an SOA.<\/p>\n","protected":false},"excerpt":{"rendered":" L’Ecole doctorale : Ecole
