Optical frequency combs in the terahertz frequency range are long-awaited frequency standards for spectroscopy of molecules and high-speed wireless communications. However, a terahertz frequency comb based on a low-cost, energy-efficient, and room...

Abstract
The capability for actual measurements—not just simulations—of the dynamical behavior of THz electromagnetic waves, including interactions with prevalent 3D objects, has become increasingly important not only for developments of various ...

Coherent control of many-electron qubits in a GaAs quantum well is demonstrated using a sequence of THz pulses. There is no signature of electron-electron interactions, generalizing the Kohn's theorem to the level of coherent dynamics.

We report on a giant Faraday effect in n-InSb probed via polarization-resolved THz time-domain spectroscopy. Rotation angles and ellipticities as large as pi and 1, respectively, were observed in a wide frequency range, making n-InSb a promising m...

Two models for the universally-observed terahertz absorption peak in carbon nanotubes are tested experimentally with infrared and terahertz spectroscopy. The curvature-induced gap theory is disproved by our observation, while plasma resonance theo...

Coherent control of cyclotron resonance in a quantum Hall system is demonstrated using a sequence of THz pulses. There is no signature of electron-electron interactions, generalizing Kohn's theorem to the level of coherent dynamics.

We use terahertz time-domain spectroscopy and Fourier-transform infrared spectroscopy to investigate carrier dynamics in large-area chemical-vapor-deposition-grown graphene, and observed that the Fermi level of graphene can be tuned by both therma...
