Generation of terahertz radiation from fe-doped InGaAsP using 800 nm to 1550 nm pulsed laser excitation

O Hatem, JR Freeman, JE Cunningham… - Journal of Infrared …, 2016 - Springer
We demonstrate efficient generation of terahertz (THz) frequency radiation by pulsed
excitation, at wavelengths between 800 and 1550 nm, of photoconductive (PC) switches …

Peak emission of terahertz waves from (110)-oriented ZnTe by interacting phase-matched phonon resonances

O Hatem - JOSA B, 2019 - opg.optica.org
We demonstrate the measurement and assignment of phonon resonances responsible for
observed peak emission of terahertz (THz) waves from (110)-ZnTe. We show that optical …

Optimizing the electro-optic detection of terahertz waves by ZnTe at 780 and 1560-nm probe-beam wavelengths

O Hatem - Journal of Nonlinear Optical Physics & Materials, 2018 - World Scientific
Investigations were made for optimizing ZnTe as a THz detector at 1560-nm probe beam
wavelength, and was compared with its performance at 780 nm. High-sensitive THz …

Phase-shifted 1.3-µm dual-mode laser diode: Toward single chip terahertz emitter

N Kim, SP Han, H Ko, HC Ryu, JW Park… - 2012 37th …, 2012 - ieeexplore.ieee.org
We have developed the λ/4 phase-shifted 1.3-µm dual mode laser as an optical beat source
of continuous-wave (CW) terahertz (THz) generation. The mode beat frequency is …
