Title (EN) ELECTRICAL CROSSTALK REDUCTION IN A HIGH-ORDER DIGITAL OPTICAL MODULATOR
(FR) RÉDUCTION DE DIAPHONIE ÉLECTRIQUE DANS UN MODULATEUR OPTIQUE NUMÉRIQUE D'ORDRE ÉLEVÉ
Abstract:
(EN) A digital optical modulator (200) including a waveguide comprising a plurality of light paths, and a plurality of phase shifter segments (208-222), each optically coupled to a light path from the plurality of light paths, configured to modulate light carried in the plurality of light paths to generate a modulated light in response to an electrical drive signal, at least two of the plurality of phase shifter segments (208-222) having the same length. A digital optical modulator (200) comprising a first waveguide arm (204) comprising a first end (228) and a second end (224), a first plurality of phase shifter segments (208-222) with at least two of the first plurality of phase shifter segments (208-222) that are the same length optically coupled to the first waveguide arm (204), and a second waveguide arm (206) optically coupled to the first waveguide arm (204) at the first end (228) and the second end (224).
(FR) L'invention concerne un modulateur optique numérique (200) qui comprend un guide d'ondes comportant une pluralité de trajets de lumière et une pluralité de segments de déphasage (208-222), couplés optiquement chacun à un trajet de lumière de la pluralité de trajets de lumière, qui est configuré pour moduler la lumière acheminée dans la pluralité de trajets de lumière afin de générer une lumière modulée en réponse à un signal d'attaque électrique, au moins deux de la pluralité de segments de déphasage (208-222) ayant la même longueur. Le modulateur optique numérique (200) comprend un premier bras de guide d'ondes (204) comportant une première extrémité (228) et une seconde extrémité (224), une première pluralité de segments de déphasage (208-222) ayant au moins deux de la première pluralité de segments de déphasage (208-222) qui sont de la même longueur, optiquement couplés au premier bras de guide d'ondes (204), et un second bras de guide d'ondes (206) optiquement couplé au premier bras de guide d'ondes (204) au niveau de la première extrémité (228) et de la seconde extrémité (224).
