LACSEA

LACSEA 2016  conference

mirSense will be present at the LACSEA meeting in Heidelberg, Germany from 25-28th July 2016 in order to present the Mirifisens project. Mathieu Carras, President of mirSense, and Gregory Maisons, Technical Director, will talk during the conferences. They will also be present at the exhibition on the booth presenting the Mirifisens project.

About LACSEA
OSA LACSEA meeting
The Laser Applications to Chemical, Security, and Environmental Analysis (LACSEA) topical meeting focuses on laser-based sensing in combustion or industrial process gases, gases that may contain chemical or biological agents, and in atmospheric gases. Sensing of liquids (e.g., aerosols) and solids (e.g., particulates or explosives) are also discussed. The rapid development of laser technologies as well as data analysis tools are paving the way for novel monitoring schemes and even real-time control in various environments. Topics cover the VUV to THz spectra range, and involve exciting new developments in analytical spectroscopy, ultrafast lasers, frequency combs, and miniaturization. Creative ideas involving new laser technologies, methodologies, and/or data analysis tools will be showcased. Special emphasis will be given to techniques exploring use of shorter (e.g., VUV) or longer (e.g., THz) spectral ranges.

About Mirifisens
Mirifisens project European Commission
During this project, mirSense will develop broadly tuneable monolithically integrated DFB QCL source to address complex molecule or multigas applications. From the user viewpoint, it must be like a standard DFB QCL in that the beam should come from a single facet. Individual lasers only able to provide limited tenability of 4-5cm-1 based on current injection tuning. In order to reach 200 cm-1 range, around 60 emitters shall be used. The emitters will be evanescently coupled to a passive wave guide. In this wave guide, a multiplexer will combine the 60 beams. The mirSense product implied in this project is multiSense.
The mid-infrared (MIR) region is emerging as the favourite wavelength band for a number of applications, including high sensitivity trace detection, chemical emission monitoring, process control, and biological sensing applications. An efficient way to get precise and reliable information is to rely on spectroscopic analysis and, among the existing technologies, Tunable Diode Laser Spectroscopy (TDLS) has been identified to be the most attractive solution due to the unique adsorption spectrum of chemicals, allowing their unambiguous detection. In the MIR region, the availability of Quantum Cascade Lasers (QCL) covering a broad portion of the spectral range (MIR, 3-12 µm), where many chemicals of interest for Safety & Security have their strongest absorption lines, has recently pushed forward the commercialization of TDLS-based detection units.

Further technology advancements are still needed in the TDLS and QCL domains, the crucial bottlenecks being the range of tuneability, the footprint, power consumption & wallplug efficiency. Besides high cost and poor versatility, these limitations set a barrier for the realization of powerful versatile detection units. To address these issues, MIRIFISENS will bring major technological advancements in the field of miniaturization, process development and heterogeneous integration.

The major technologic achievements proposed will address the issues of sensitivity & selectivity, multi-gas capabilities, compactness, efficiency and cost effectiveness as specified by a number of selected Safety & Security applications. These achievements will be tested and validated for these applications. MIRIFISENS will deliver a new class of sensors with superior tuneability, better portability and extended detection capabilities, changing radically the current landscape of MIR chemical sensing spectroscopy.
