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…

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…

Hole trap, leakage current and barrier inhomogeneity in (Pt/Au)-Al_0.2Ga_0.8N/GaN heterostructures

Salah Saadaoui, Olfa Fathallah, Fethi Albouchi, Mohamed Mongi Ben Salem, Christophe Gaquière, Hassen Maaref

In this work, we report on the electrical characteristics of Pt/Au Schottky contacts to Al_0.2Ga_0.8N/GaN heterostructures. Indeed, we have realized gate current-voltage I(V) and deep level transient spectroscopy (DLTS) measurements. The behavior study of…

A Suspended Silicon Terahertz platform with low loss waveguide and high Q Photonic Crystal cavities

Elias Akiki, Mattias Verstuyft, Guillaume Ducournau, Benjamin Walter, Estelle Mairiaux, Marc Faucher, Jean-Francois Lampin, Bart Kuyken, Mathias Vanwolleghem

A high Q optical resonator and ultra-low losses of a silicon suspended waveguide, are experimentally measured and presented, in order to demonstrate the working of a designed photoacoustic terahertz gas sensor presented in our previous work.

The Gouy phase shift in terahertz time-domain spectroscopy and its experimental estimation, modelling and compensation

Pierre Kolejak, Kamil Postava, Martin Micica, Mathias Vanwolleghem, Jaromir Pistora

Spatial properties of pulsed beams become more important in the terahertz range, which causes that reference and sample measurements can differ in the spectral dependent complex phase called the Gouy phase. It originates from propagation of the beam wavefront close to the focus. In such a case, the…

Frequency noise and phase-locking of a quantum cascade laser-pumped, 1.073THz molecular laser using a 1560nm frequency comb

S Barbieri, Jean-Francois Lampin, A. Pagies, G. Santarelli, J. Hesler, W. Hansel, R. Holzwarth

Abstract: We report the measurement of the frequency noise power spectral density (PSD) of a THz molecular laser (ML) pumped by a mid-infrared (MIR) quantum cascade laser (QCL). This is obtained by beating the ML frequency with the harmonic of the repetition rate of a 1560nm frequency comb (FC). We…
