Photonic THz mixers based on iron-doped InGaAs embedded in a plasmonic microcavity

Charbel Tannoury, Victor Merupo, Giuseppe Di Gioia, Vanessa Avramovic, David Troadec, Jean-François Lampin, Guillaume Ducournau, Steffen Breuer, Björn Globisch, Stefano Barbieri, Robert B Kohlhaas, Emilien Peytavit

We present an optoelectronic mixer for the terahertz (THz) frequency-domain based on an iron-doped InGaAs layer integrated in a plasmonic microcavity. We show that this structure, under 1550-nm-wavelength illumination, allows for more than 70% absorption efficiency in a 220 nm-thin InGaAs absorber…

CW Laser Emission up to 5 THz Using Optically Pumped Water Molecules

L. Juppet, A. Khabbaz, Gaël Mouret, Jean-Francois Lampin, Olivier Pirali

In this work we discuss the use of a new molecule (deuterated water, D 2 O) to produce THz radiation using a midinfrared quantum cascade laser (MIR-QCL) pumped molecular laser. The molecular gain factor was used to determine the most favorable laser lines and several laser lines were measured up to…

High precision molecular laser frequency measurements using a THz frequency comb

A. Khabbaz, L. Juppet, O. Pirali, Jean-Francois Lampin, Francis Hindle, Gaël Mouret

Molecular lasers are powerful sources of continuous-wave THz radiation that can be used as local oscillators for heterodyne receivers. In this work we show that it is possible to measure precisely their emission frequency using a simple setup based on a THz frequency comb referenced to a microwave…

Flight-Testing of a MEMS Wall Shear Stress Thermal Sensor on a Microlight Aircraft

C. Ghouila-Houri, T. Arnoult, A. Mazzamurro, S. Kern, R. Viard, D. Teillet, E. Palfi, E. Garnier, Abdelkrim Talbi, P. Pernod

This paper reports the realization of thermal MEMS (Micro Electro-Mechanical Systems) sensors designed for wall shear stress measurement during real flight on a microlight aircraft. Based on constant temperature anemometry and calorimetric principle, the micro-sensors measure the viscous shear…
