DEVICE AND SYSTEM FOR MODULATING THE PHASE OF AN OPTICAL SIGNAL, BASED ON GRAPHENE AND/OR CARBON-BASED NANOSTRUCTURED MATERIALS
Disclosed are a device and system for modulating the phase of an optical signal, based on graphene and/or carbon-based nanostructured materials. The device and system for modulating the phase of an optical signal, based on graphene, essentially comprise: a graphene-based electro-optical device in which light interacts with the graphene, such that a variation of the phase of the optical signal is produced, without significant variation of the amplitude or intensity thereof; an optical interface that allows the phase variation produced in the optical signal to be analysed or monitored; and an electronic interface that allows the graphene to be acted upon by modifying the properties thereof in order to modify the phase of the optical signal, without affecting the intensity of same.
