Advanced Optical Materials, 2020
The terahertz (THz) region of the electromagnetic spectrum spans the gap between optics and electronics and has historically suffered from a paucity of optoelectronic devices, in large part because of inadequate optical materials that function in this ...

Full-field THz polarimetric imaging with THz quantum cascade laser and THz imager
2019 44th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), 2019We demonstrate full-field THz polarimetric imaging with THz quantum cascade laser and THz imager. In contrast to point-scanning THz polarization imaging based on THz-TDS, the demonstrated method does not need mechanical stages for time-delay scanning and sample-position scanning.

Pressure-broadening in the THz frequency region: The 1.113 THz line of water
Journal of Quantitative Spectroscopy and Radiative Transfer, 2008It is well established that water plays a fundamental role in various atmospheric phenomena and that the accuracy of its collisional broadening parameters has a crucial influence on reduction of remote sensing data. Nevertheless, in this field the experimental data are still scarce and consequently the estimates reported in spec- troscopic databases ...

THz nonlinearity of water observed with intense THz pulses
Conference on Lasers and Electro-Optics 2010, 2010We reveal THz nonlinearity of liquid water using intense monocycle THz pulse. Single THz pulse response and THz pump-probe spectroscopy show the breaking and recovering of hydrogen bonding network in water molecules.

THz spectroscopy for THz spintronics (Conference Presentation)
Spintronics IX, 2016Controlling currents using circularly polarized light and spin-orbit coupling could lead to the development of ultrafast spintronic devices driven by laser pulses and operating at the femtosecond timescale. Here we demonstrate that such a helicity dependent photocurrent can be generated in metallic heterostructures consisting of a single ferromagnetic ...

THz and Photonic Seamless Communications
Journal of Lightwave Technology, 2019Terahertz (THz) wave can offer over 100-Gb/s wireless transmission by the use of wide spectrum. Due to features of high-frequency waves such as lightwaves, THz can have high directivity.
