1.  Dr. Grégory Maisons, Alcatel-Thales III-V Lab, FRANCE
Late-Breaking Results: Monolithic tunable single source in the Mid-IR for Spectroscopy
Speaker Biography: Grégory Maisons: is born in 1983. He graduated from the University of Paris Sud XI Orsay (Physics) in 2007 and from the Ecole Nationale Supérieur de Grenoble (nano and micro opto-electronics). Then he graduated from the University of Joseph Fourier in 2010 (PhD degree in Condensed Matter and Optical Radiation). He was engaged, since 2011, in the development of novel quantum cascade laser devices for spectroscopy and chemical sensing at the III-V lab. His current research interests include optical simulations of single frequency quantum cascade lasers, monolithically integrated new functionalities and novel processing of diodes.

Summary: In the Mid-Infrared the Distributed Feedback (DFB) Quantum Cascade Lasers (QCL) are among the favoured sources for the Laser Spectroscopy. In order to detect complex molecules or a set of simple molecules, one needs a narrow-linewidth tunable source suitable to scan few tens of wavenumbers. Monolithic tuneable sources are very appealing for spectroscopy applications because of the compactness, the robustness and the usability. A single DFB QCL has a limited tuneability, the two main leverages being the temperature and the current.
