Terahertz Modulation using Micro- and Nano- Apertures on VO{sub}2 Thin Film

摘要

We report on the terahertz modulation based on the micro- and nano- sized apertures with metal-insulator phase transition of VO{sub}2 thin film. Terahertz wave transmission through subwavelength apertures is controlled by temperature driven refractive index change of VO{sub}2 substrate.
