Title (EN) HIGH GAIN RESONANT MODULATOR SYSTEM AND METHOD
(FR) SYSTEME DE MODULATEUR DE RESONANCE A GAIN ELEVE, ET PROCEDE ASSOCIE
Abstract:
(EN) An optical resonant modulator (100) includes an optical ring resonator (117) and an optical loop (112) that is coupled to the optical ring resonator by two couplers (118, 119) . The optical ring resonator can have a hybrid design in which the ring resonator is formed on an electro-optically passive material and the optical loop is formed on an electro-optically active material. An amplification section can be inserted between the electro-optically passive and the electro-optically active sections. In analog applications, an optical resonator includes a Mach Zehnder interferometer section having an input and an output, with a feedback path coupling the output to the input. Applications of the optical modulator of the invention, and a method for modulating an optical signal also are disclosed.
(FR) Un modulateur de résonance optique comprend un résonateur annulaire optique et une boucle optique qui est couplée au résonateur annulaire optique au moyen de deux coupleurs. Le résonateur annulaire optique peut être d'un concept hybride, dans lequel le résonateur annulaire est formé sur un matériau électro-optiquement passif, et la boucle optique est formée sur un matériau électro-optiquement actif. Une section d'amplification peut être insérée entre les sections électro-optiquement passives et les sections électro-optiquement actives. Dans des applications analogiques, un résonateur optique comprend une section à interféromètre de Mach Zehnder ayant une entrée et une sortie, avec parcours de rétroaction couplant la sortie à l'entrée. L'invention concerne en outre des applications du modulateur optique de l'invention, ainsi qu'un procédé de modulation d'un signal optique.
