    摘要: The present invention relates to an electro-optical modulator, particularly to a double layer graphene modulator having an optimized arrangement to provide both a large optical bandwidth and a high optical transmission for light travelling through an optical waveguide (W) of the modulator, wherein at least one of a top (Gu) and a bottom (Gb) graphene sheets extends along a X-direction:
    - above part of the width of the optical waveguide (W), wherein said part ranges from 50% to 100% of the width of the optical waveguide (W); or
    - completely above the whole width of the optical waveguide (W), and beyond through a respective further projecting portion with a length, along the X direction, of up to 25% of the optical waveguide (W) width.
    The present invention also relates to a method for obtaining the electro-optical modulator of the invention.
