Graphene-based electro-optical modulators integrated into polymer waveguide with three dielectric materials proposals

摘要

and boron nitride, hBN. By varying the thickness of the dielectric material, it was possible to improve the extinction ratio, modulation frequency and reduce the switching voltages requirements. By considering a bottom cladding, it was possible to increase the light interaction with the graphene and obtain higher modulation frequencies. In the case of the device with HfO
