Real-Time, Subwavelength Terahertz Imaging
Source abstract
Abstract
The fields of biosensing, nanospectroscopy, and plasmonics have great potential for near-field terahertz (THz) technology. In this work, we demonstrate that electro-optic (EO) imaging combined with the brightness of recently developed intense THz sources permits the imaging of subwavelength-size samples without compromising spatial resolution or acquisition time. We report on recent advances in this field and current achievements in optimizing spatial resolution and acquisition time. Near-field imaging demonstrations on field enhancement in metallic-based resonators and metamaterials are also discussed. This development will accelerate our comprehension of subwavelength light-matter interactions at THz frequencies and enable new spectroscopic applications.
