In this paper some preliminary results pertaining to the design and fabrication of rare-earth doped chalcogenide microresonators for lasing in mid-infrared (Mid-IR) wavelength range are illustrated. The unique properties of chalcogenide glass and the Whispering Gallery Mode (WGM) resonances make possible to obtain light emission via rare-earth transitions at long wavelengths. As example, a light source based on chalcogenide glass doped with Er3+ is investigated via a home-made numerical model based on the coupled mode theory and solving the rare-earth rate equations. A number of promising applications in different areas such as biology, molecular spectroscopy and environmental monitoring are feasible.

Abstract
In this paper some preliminary results pertaining to the design and fabrication of rare-earth doped chalcogenide microresonators for lasing in mid-infrared (Mid-IR) wavelength range are illustrated. The unique properties of chalcogenide glass and the Whispering Gallery Mode (WGM) resonances make possible to obtain light emission via rare-earth transitions at long wavelengths. As example, a light source based on chalcogenide glass doped with Er3+ is investigated via a home-made numerical model based on the coupled mode theory and solving the rare-earth rate equations. A number of promising applications in different areas such as biology, molecular spectroscopy and environmental monitoring are feasible.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
