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…

LT-GaAs-based photomixers with >2 mW peak output power up to 320 GHz

F Bavedila, Etienne Okada, Jean-Francois Lampin, Guillaume Ducournau, Emilien Peytavit

It is shown in this communication that a LT-GaAs photomixer based on an optically resonant cavity is able to generate peak output powers above 2 mW up to 320 GHz when it is driven by optical pulses of 5 ns width at a repetition rate of 10 MHz.

Linearity and robustness evaluation of 150-nm AlN/GaN HEMTs

Mehdi Rzin, Matteo Meneghini, Fabiana Rampazzo, V. Gao Zhan, Carlo de Santi, Riad Kabouche, Malek Zegaoui, F Medjdoub, Gaudenzio Meneghesso, Enrico Zanoni

We report on linearity and robustness of AlN/GaN HEMTs with ultra-thin 4 nm AlN barrier for millimeter wave range applications. Static and dynamic I-V characteristics feature high peak transconductance (g mpeak) of 385 mS/mm, and the transconductance exhibits small changes with gate bias. Semi on-…

Modified AFM-tip for Infrared and THz near field microscopy

Tahsin Akalin

Near field microscopy is commonly achieved thanks to the exaltation of the field between a tip and the sample. The free space electromagnetic wave at infrared or THz frequencies is focused in this extremely small area compared to the wavelength. In many cases, the probe is a classical AFM-tip which…

Terahertz pulsed-field magneto-spectrometer at room-temperature

Jean-Francois Lampin, Antoine Pagies, S Barbieri, L. Desplanque, Xavier Wallart, Jeffrey Hesler, Oleksiy Drachenko, Jean Léotin

We have developed a compact pulsed-field THz magneto-spectrometer based on a THz molecular laser and heterodyne detection both at room-temperature. The recently developed continuous-wave THz laser uses mid-IR-pumped ammonia as active medium. The receiver is based on a subharmonic mixer pumped by a…

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…
