The mid-infrared spectral region is a great technical and scientific interest in numerous research field and applications. Among these studies, the generation of mid-infrared supercontinuum in fibers has attracted strong interest in the last decade, because of unique properties such as broad wavelength-coverage and brightness. In this work, a cascaded supercontinuum generated in a fluoride and a chalcogenide fiber spanning from 2 to 10 µm has been used for the detection of infrared signatures of organic compounds. Those results open a new way for remote sensing and spectroscopy in the mid-IR.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
