Abstract
An electrically controllable terahertz (THz) plasmonic crystal waveguide based on double-structured Schottky grating arrays has been fabricated and investigated. The experiment and simulation show two different resonance behaviors of a discrete jump and a continuous shift when applying positive and negative bias, respectively. THz modulations with a 15 dB modulation depth have been realized in the frequency range of 2.2−3.2 THz. Furthermore, these modulation behaviors have been interpreted as the generation and shift of the plasmonic band structures accompanying with the spatial modulations of the Schottky barriers in this device. This active THz device can be feasibly applied into THz application systems.
