Abstract
This paper proposed a polarization independent terahertz modulator based on gold-Si metamaterials with symmetric structure, and aimed to modulate terahertz wave in communication systems. The transmission properties have been investigated in terahertz regime. We find that the resonance frequency of this device can be actively controlled by pump laser. The numerical simulations and experiments with OPTP system show that this device acts as a modulator with intensity modulation depth of 70% by gold structure.
