Résumé
The fabrication and the characterization of Sb-based Mid-Infrared emitting VCSELs are described in this paper. Both extemal-cavity and microcavity optically-pumped devices exhibit very high performances particularly well-adapted for trace gas detection by laser spectroscopy. Concerning electrically-pumped Sb-based VCSELs, the first results obtained with an hybrid dielectric-semiconductor structure are presented. However, such devices remain less mature than similar optically-pumped laser and only microcavity-enhanced electroluminescence could be observed near 2.3 mu m at room temperature.
