Over the past three decades a new spectroscopic technique with unique possibilities has
emerged. Based on coherent and time‐resolved detection of the electric field of ultrashort …

Terahertz frequency radiation possesses a unique combination of desirable properties for
noninvasive imaging and spectroscopy of materials. This includes the ability to obtain …

Even though the terahertz spectrum is well suited for chemical identification, material
characterization, biological sensing and medical imaging, practical development of these …

Terahertz (THz) detectors play an increasing role in different areas of human activities (eg,
security, biological, drugs and explosions detection, imaging, astronomy applications, etc.) …

We present a photoconductive terahertz emitter that incorporates three-dimensional
plasmonic contact electrodes to offer record high optical-to-terahertz power conversion …

Conceived over 30 years ago, photoconductive (PC) emitters have proved essential in the
development and spread of terahertz technology. Since then, not only have they been used …

The photo-Dember effect is a source of impulsive THz emission following femtosecond
pulsed optical excitation. This emission results from the ultrafast spatial separation of …

We demonstrate broadband (20 THz), high electric field, terahertz generation using large
area interdigitated antennas fabricated on semi-insulating GaAs. The bandwidth is …

In this review, we discuss the rich ultrafast response at terahertz (THz) frequencies of two-
dimensional (2D) materials. Thanks to their unique optoelectronic properties and …

We report the optical characterization of low temperature (LT)-GaAs and Semi Insulating (SI)-
GaAs based dipole types Photoconductive (PC) antennas with gap of 5 μm for the …
