Microscale whispering gallery-mode lasers for sensing applications (Conference Presentation)
Author(s): Tindaro Ioppolo

Paper Abstract

Micro-scale whispering gallery mode lasers are demonstrated as sensors for remote sensing. We exploit its potential applications in the field of biological and mechanical engineering and different remote sensing applications will be reported. These micro-resonators are fabricated by mixing a solution of rhodamine 6G and methanol with different polymers. The micro-resonators are optically pumped using a Nd:YAG laser and their emission spectrum is observed using a spectrometer. The excited optical resonances are very sensitive to a change in the morphology of the resonators. Therefore, any perturbation of the morphology of the resonator such as size shape and index of refraction leads to a shift of the frequency of the optical resonances. By tracking the shift of the optical resonances, the external physical effect causing the morphology change can be monitored.
