Book ChapterDOI
Terahertz access to the nanoworld
TL;DR: In this article, the authors report on time-resolved terahertz near-field microscopy with a spatial resolution of 150 nm and identify a novel imaging mechanism, which allows for nanoscale THz studies of organic and inorganic materials.
Proceedings ArticleDOI
Opto-electronic control of terahertz metamaterials
TL;DR: In this article, the authors demonstrate external control of metamaterials operating at terahertz frequencies through photodoping of semiconducting substrates, used to support metamatter arrays, and show ultrafast switching times.
Proceedings ArticleDOI
Terahertz access to the nanoworld
TL;DR: In this paper, a time-resolved terahertz near-field microscopy with nanometer spatial resolution is presented. And a novel imaging mechanism is discovered that allows for near field microscopy of organic and inorganic materials.
Proceedings ArticleDOI
Active metamaterial diffraction grating
N. Karl,Kimberly S. Reichel,Hou-Tong Chen,Antoinette J. Taylor,Igal Brener,Alexander Benz,John L. Reno,Rajind Mendis,Daniel M. Mittleman +8 more
TL;DR: In this paper, a switchable diffraction grating based on active metamaterials for terahertz modulation was proposed and tested, which permits operation of the device as a narrowband high-contrast modulator.
Journal ArticleDOI
Ultrafast terahertz emission from emerging symmetry-broken materials
Jacob Pettine,P. V. Padmanabhan,Nicholas Sirica,Rohit P. Prasankumar,A. J. Taylor,Hou-Tong Chen +5 more
TL;DR: In this article , the authors survey a selection of recent studies that utilize terahertz (THz) emission spectroscopy to uncover basic properties and complex behaviors of emerging materials, including strongly correlated, magnetic, multiferroic, and topological systems.
