Abstract :
We demonstrate electro-optical modulation of mid-infrared Si photonic crystal cavities by the electrostatic doping of graphene. A wavelength shift of 4 nm is demonstrated around a wavelength of 4.47 μm, demonstrating the feasibility of on-chip electro-optic modulation for the mid-infrared wavelength region.
