Optically tunable plasmon-induced transparency in terahertz metamaterial system
Source abstract
Abstract
Abstract An optically tunable terahertz modulator based on plasmon-induced transparency (PIT) metasurface was investigated theoretically and experimentally. It was found that, upon near infrared photoexcitation, the resonance degree of the transparent window displayed a decreasing tendency and emerged a weaker blue-shift phenomenon. And when the optical pump power was tuned to 1000 mW, the resonant transmission modulation depth reached to 81.68% at 0.81 THz. Furthermore, a coupled Lorentz oscillator model was adopted to analyze the near field interaction of the resonances.
