Résumé
Abstract An extensive characterization of the spectral properties of a largely tunable laser in the 1.56-um spectral range is reported. This device combines a vertical-cavity surface-emitting laser (VCSEL) with a micro-machined(MEMS) Bragg mirror in a very compact arrangement. The
large tunability obtained by an electro-thermal actuation of the MEMS mirror makes this device very attractive for high-resolution spectroscopy. Relevant laser parameters for the implementation of wavelength modulation spectroscopy techniques in gas sensing, such as tuning and modulation properties, are presented. A preliminary gas spectroscopy
experiment performed with this laser is also shown.
