Terahertz modulator based on graphene embedded waveguide
We reported a novel terahertz modulator based on graphene embedded waveguide. Comparing to previous solution, the terahertz wave matter interaction in the modulator structure is enhanced greatly. In theory, the modulation depth can be nearly 100% as the simulation results show. Experimental characterisations are carried out through continuous terahertz wave system and the terahertz time domain spectroscopy (TDZ) system respectively. The best experimental modulation depth is 29.53% which is much larger than state of art results.
