Title (EN) ELECTRO-OPTICAL INTEGRATED TRANSMITTER CHIP FOR ARBITRARY QUADRATURE MODULATION OF OPTICAL SIGNALS
(FR) PUCE D'EMETTEUR-RECEPTEUR ELECTRO-OPTIQUE INTEGRE POUR MODULATION EN QUADRATURE ALEATOIRE DE SIGNAUX OPTIQUES
Abstract: front page image
(EN)An optical device includes, a first Mach-Zehnder modulator (105, 106) that produces a first output and a second Mach-Zehnder modulator (205, 206) which produces a second output. A splitter (212 )couples the first and second Mach-Zehnder modulators. A combiner (213) combines the first and second outputs. A phase shifter (107, 207) is coupled to the first and second Mach-Zehnder modulators. The first Mach-Zehnder modulator, second Mach-Zehnder modulator, splitter, combiner and the phase shifter are each formed as part of a single chip made of electro-optical material. Such two similar optical device integrated together with polarization combiner provide a two-polarization performance.
(FR)Un dispositif optique comprend un premier et un second modulateurs Mach-Zehnder produisant une première et une seconde sortie, respectivement. Un coupleur relie les premier et second modulateurs mach-Zehnder. Un combinateur combine les première et seconde sorties. Un déphaseur est couplé aux premier et second modulateurs Mach-Zehnder. Le premier modulateur Mach-Zehnder, le second modulateur Mach-Zehnder, le coupleur, le combinateur et le déphaseur font chacun partie d'une puce unique faite d'un matériau électro-optique. Deux dispositifs otptiques analogues intégrés l'un à l'autre avec combinateur de polarisation permettent d'obtenir une bi-polarisation.
