Claim 9:
10. The electro-optical modulator according to claim 1, wherein:
said sheet of a first dielectric material extends along the X-direction at least within an area overlapped by both the top and the bottom graphene sheets; and
a bottom sheet of said second dielectric material covering the lower face of the top graphene sheet or a top and bottom sheets sandwiching the top graphene sheet, contact the second electrode and extend, along the X-direction, up to at least just above and just below, respectively, a top graphene free edge, and/or
a top sheet of said second dielectric material covering the upper face of the bottom graphene sheet or a top and a bottom sheets of the second dielectric material sandwiching the bottom graphene sheet, contact the first electrode and extend, along the X-direction, up to at least just above or just above and just below, respectively, a bottom graphene free edge.
