[Invited] Thermoacoustic sound generation model in porous nanomaterials

Pierre Guiraud, Stefano Giordano, Olivier Bou Matar, Raphael Lardat, Philippe Pernod

Traditional sound generation transducers are using a magnet/coil/membrane system to induce a particle velocity boundary condition to move the air in order to produce sound. Piezoelectric devices are also electromechanical transducer that are also used for sound generation in cases where common…

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…

Broadband terahertz heterodyne spectrometer exploiting synchrotron radiation at sub-megahertz resolution

O. Pirali, Z. Buchanan, Sophie Eliet, M.-A. Martin-Mel, J. Turut, Francis Hindle, P. Roy, Jean-Francois Lampin, Gaël Mouret

A new spectrometer on the AILES beamline of the SOLEIL synchrotron facility to achieve sub-MHz resolution in the THz and far-IR regions is currently being developed. Thanks to a dedicated heterodyne detection by use of a new kind of molecular laser as local oscillator along with a Fast Fourier…

Towards broadband THz spectroscopy and analysis of sub-wavelength-size biological samples

Sergey Mitryukovskiy, Melanie Lavancier, Flavie Braud, Yue Bai, Emmanuel Dubois, Jean-Francois Lampin, Romain Peretti

We report on our recent progress toward bio-photonic applications of terahertz time-domain spectroscopy. First, we developed a technique for the confinement of broadband terahertz pulses to a sub-wavelength-volume, and will present its applications to study biological samples. Second, we will…

Optically-Pumped Terahertz Sources and Applications

S Barbieri, Joan Turut, Antoine Pagies, Jean-Francois Lampin

Abstract: Despite several progress generation of electromagnetic power in the THz range is still underdeveloped compared to the other frequency bands. Direct THz generation poses fundamental and practical problems very difficult to solve. Generating THz using sources from lower or higher…
