La ma\u00eetrise des peignes de fr\u00e9quences optiques a r\u00e9volutionn\u00e9 la m\u00e9trologie des fr\u00e9quences. En outre, de la spectroscopie aux t\u00e9l\u00e9communications num\u00e9riques, en passant par la mesure de distance, les applications de cette technologie foisonnent. Pourtant, les peignes de fr\u00e9quences disponibles dans le commerce demeurent relativement co\u00fbteux et encombrants. L\u2019optique int\u00e9gr\u00e9e pourrait r\u00e9pondre au d\u00e9fi de leur accessibilit\u00e9. En s\u2019inspirant des proc\u00e9d\u00e9s de fabrication de circuits int\u00e9gr\u00e9s \u00e9lectroniques, des circuits photoniques entiers peuvent d\u00e9sormais \u00eatre r\u00e9alis\u00e9s sur des puces de quelques millim\u00e8tres carr\u00e9s. La production massive de tels circuits permettrait en plus de r\u00e9duire le co\u00fbt de nombreux syst\u00e8mes optiques ou opto-\u00e9lectroniques, dont les sources de peignes de fr\u00e9quences.<\/p>\n\n\n\n
Apr\u00e8s avoir d\u00e9taill\u00e9 le contexte dans lequel s\u2019inscrivent les peignes de fr\u00e9quences, d\u2019une part, et l\u2019optique int\u00e9gr\u00e9e, d\u2019autre part, je pr\u00e9senterai deux travaux de recherche portant sur la g\u00e9n\u00e9ration de peignes de fr\u00e9quences sur puce.<\/p>\n","protected":false},"excerpt":{"rendered":"
