2018 43rd International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), 2018
In this work, we demonstrate novel THz detectors and modulators based on semiconductor nanowires. We show that single nanowire PC THz receivers exhibit excellent sensitivity, high SNR of 40, and a broad detection bandwidth up to 2 THz, comparable to the bulk InP PC receivers. We also demonstrate ultrafast THz modulation by GaAs nanowire polarisers with

Microspectroscopy with Terahertz bioMEMS
SPIE Proceedings, 2006Biological applications require more and more compact, sensitive and reliable microsystems. We will present solutions in order to realize a "microspectroscopy" up to Terahertz frequencies of various biological entities (living cell, neurons, proteins...). We investigate these entities in liquid phase.

Subsurface sensing at sub-terahertz and terahertz frequencies
Proceedings of the XIII Internarional Conference on Ground Penetrating Radar, 2010Development of millimeter and sub-millimeter wavelengths technologies is of great interest lately, especially for application in terahertz imaging due to bringing high resolution. In our paper we consider a tomography approach for obtaining 3-D imaging in frequency range from 100 GHz up to 325 GHz.

Terahertz technology applications, sensors, and sources are briefly reviewed. Emphasis is placed on the less familiar components, instruments, or subsystems. Science drivers, some historic background, and future trends are also discussed.

Terahertz Generation and Acceleration
CLEO Pacific Rim Conference, 2018Laser based multi-cycle THz generation by difference frequency mixing has been pushed to optical to THz conversion efficiencies close to 1%. This opens up the possibility to implement THz driven electron and X-ray sources.

Terahertz antennas present a different set of challenges to the antenna designer typically striving for very high performance while at the very limit of the chosen fabrication process. Many of the same design techniques used at lower frequencies are still applied, but fabrication constraints impose significant limitations on the type of structure that ...
