Title
(EN) POLARIZATION INDEPENDENT REFLECTIVE MODULATOR
(FR) MODULATEUR DE RÉFLEXION INDÉPENDANT DE LA POLARISATION
Abstract
(EN)
An apparatus and a method are provided. The apparatus (100) comprises an optical input (147) configured to receive an optical carrier (141), an polarization beam splitter (155) configured to forward a first polarized component of the optical carrier (141) along a first light path (156), and forward a second polarized component of the optical carrier (141) along a second light path (158), and an optical modulator (159). The first polarized component comprises a first polarization (TE) that is perpendicular to a second polarization (TM) of the second polarized component upon exiting the optical splitter (155). The optical modulator (159) is coupled to the first light path (156) and the second light path (158), and is configured to modulate the first polarized component of the optical carrier and the second polarized component of the optical carrier.

L'invention concerne un appareil et un procédé. L'appareil (100) comprend une entrée optique (147) conçue pour recevoir une porteuse optique (141), un séparateur de faisceau de polarisation (155) conçu pour transmettre une première composante polarisée de la porteuse optique (141) le long d'un premier trajet de lumière (156) et pour transmettre une seconde composante polarisée de la porteuse optique (141) le long d'un second trajet de lumière (158) et un modulateur optique (159). La première composante polarisée comprend une première polarisation (TE) qui est perpendiculaire à une seconde polarisation (TM) de la seconde composante polarisée lors de la sortie du séparateur optique (155). Le modulateur optique (159) est couplé au premier trajet de lumière (156) et au second trajet de lumière (158) et est conçu pour moduler la première composante polarisée de la porteuse optique et la seconde composante polarisée de la porteuse optique.
