Terahertz radiation has wide array of potential uses, however, finding robust and tunable sources of terahertz radiation has been challenging. Here, Cong et al demonstrate a room temperature terahertz source composed of a two-dimensional hybrid metal

Next-generation terahertz (THz) sources demand lightweight, low-cost, defect-tolerant, and robust components with synergistic, tunable capabilities. However, a paucity of materials systems simultaneously possessing these desirable attributes and func

Conference on Lasers and Electro-Optics.
Reversible, 200 fs optical switching of carbon nanotubes is demonstrated by utilizing Coulombic many-body effects, strong exciton binding and quantum memory in Coulombic scattering which together eliminate pure dephasing of coherences.

Ultrafast spectroscopy of semiconducting carbon nanotubes reveals transient modifications in the lowest exciton absorption peak. Below-gap excitation induces a blue-shift due to the optical Stark effect, while a Rabi doublet appears under resonant ex

An applied magnetic field greatly modifies the states and properties of excitons, or bound electron-hole pairs, in photoexcited semiconductors. Depending on the strength of the magnetic field, as well as the density and temperature of the excitons, a

High-quality thin films of highly aligned semiconducting single-wall carbon nanotubes have been recently demonstrated. They have excellent absorption and photoluminescence properties; however, fast nonradiative recombination of carriers prevents thei

Superfluorescence (SF) is a many-body process in which a macroscopic polarization spontaneously builds up from an initially incoherent ensemble of excited dipoles and then cooperatively decays, producing a delayed pulse of coherent radiation. SF aris
