2D Materials Coupled to Hybrid Metal-Dielectric Waveguides for THz Technology
2018
We present hybrid metal-dielectric waveguides coupled to 2D materials that provide strong light-matter interaction at THz frequencies. We show that the strength of the electric field components are maximized at the top of the dielectric strip on which the 2D material is deposited. We predict 100 % modulation of THz light by tuning the Fermi level of a graphene sheet deposited onto an 1mm-long hybrid metal-dielectric waveguide. We also show the potential of graphene multilayers coupled to these waveguides for achieving lasing at THz frequency.
