Terahertz radiation confinement using metallic resonators

T. Hannotte, M. Lavancier, S. Mitryukovskiy, Jean-Francois Lampin, Romain Peretti

We designed, fabricated and characterized a micro-resonator in the terahertz range to increase light matter interaction using near-field optics. The goal of our device is to confine a THz electric field in a volume smaller than the diffraction limit to enhance light matter interaction with…

Silicon Based Diode Noise Source Scaling For Noise Measurement Up To 325 GHz

H. Ghanem, J-C. Azevedo-Goncalves, Sylvie Lepilliet, D. Gloria, Christophe Gaquière, Francois Danneville, Guillaume Ducournau

In this article, we investigate the use of silicon-based diode for millimeter-wave noise generation. A test bench setup was characterized to perform broadband noise measurements up to 325 GHz. A noise receiver is assembled and its Noise Figure (NF) was extracted using cryogenic Hot/Cold…

Retrieving permittivity model parameters for polar liquids and multilayer systems through THz-TDS time-trace data analysis

Melanie Lavancier, Sergey Mitryukovskiy, Nabil Vindas, Jean-Francois Lampin, Romain Peretti

We present new features of the Fit@TDS software for the analysis of polar liquids and multilayer systems. We also show that the modeling of the absorption coefficient of polar liquids can be improved around 2 THz. Hence, this software will enable us to retrieve the parameters of the models…

Terahertz near-field imaging using batch-fabricated cantilevers with 70 μm long tips

B. Walter, E. Mairiaux, D. Vignaud, Sophie Eliet, Jean-Francois Lampin, Marc Faucher

Batch-fabricated atomic force microscopy cantilevers with tip longer than 70 μm are reported. They are designed to increase terahertz focusing in scattering optical nearfield imaging. Terahertz imaging of graphene samples with sub-100 nm features is presented.

Tunable filter design for IR hyperspectral imaging

Justine Champagne, Samuel Dupont, Joseph Gazalet, Jean-Claude Kastelik

The use of wide-angle Acousto-Optic Tunable Filter (AOTF) for hyperspectral imaging is considered: the diffraction efficiency is calculated around a usual diffraction plane for two degrees of freedom (azimuthal and transverse angle). The efficiency evolution is also examined over a wide wavelength…
