Terahertz (THz) time-domain emission spectroscopy was performed on layered 2H-MoSe 2 and 2H-WSe 2. The THz emission shows an initial cycle attributed to surge currents and is followed by oscillations attributed to coherent interlayer phonon modes. To

We demonstrate that terahertz radiation can be generated from titanium-diffused magnesium oxide-doped lithium niobate optical strip waveguides when pumped by a single laser source with a wavelength of 1.55 μm. Titanium-in-diffusion was performed on

We demonstrate that titanium-doped lithium niobate strip optical waveguides can act as terahertz emitters. Terahertz pulses were produced by pumping with a femtosecond laser at a wavelength of 1.55 μm via the prism-coupled Cherenkov-phase matching s

Terahertz generation in a thin (100-µm thick) GaAs crystal sandwiched between the walls of a metallic tapered parallel plate waveguide at its narrow end and pumped by a 1560-nm femtosecond laser has been experimentally studied. The terahertz radiati

An externally applied magnetic field was used to induce increased photocarrier transport along the high mobility channel in GaAs/AlGaAs modulation-doped heterostructures (MDH). The terahertz (THz) emission from GaAs/AlGaAs MDH increases with increasi

2020 45th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz).
The effect of using spintronic antennas on the generated THz wave was investigated. Compared to the antenna-free spintronic bilayer, a ~98% improvement was observed on THz emission amplitude when using a thicker Pt diabolo-shaped antenna as the radia

We report the molecular beam epitaxy growth of high-quality p-InAs thin films evaluated in the context of 1.55 μm femtosecond laser-excited THz emission efficiency. The presence of p-InAs is confirmed via scanning electron microscopy and X-ray diffr
