We present linear and non linear optical applications of solid and hollow silica microresonators. Hollow microresonators or microbubble resonators combine the unique properties of whispering gallery mode resonators (WGMR) with the intrinsic capability of integrated microfluidics. Microbubbles were filled with water and aqueous solutions of ethanol in order to test the refractive index sensing capabilities of such resonators. We also tested the potential of microbubbles as nonlinear enhancement platform of both the filling material (Rhodamine 6G and Fluorescein) and the glass bubble.

Abstract
We present linear and non linear optical applications of solid and hollow silica microresonators. Hollow microresonators or microbubble resonators combine the unique properties of whispering gallery mode resonators (WGMR) with the intrinsic capability of integrated microfluidics. Microbubbles were filled with water and aqueous solutions of ethanol in order to test the refractive index sensing capabilities of such resonators. We also tested the potential of microbubbles as nonlinear enhancement platform of both the filling material (Rhodamine 6G and Fluorescein) and the glass bubble.File in questo prodotto:
