摘要

We report Raman lasing and the optical analog of electromagnetically-induced-transparency (EIT) in a whispering-gallery-mode (WGM) microtoroid resonator embedded in a low refractive index polymer matrix together with a tapered fiber coupler.The microtoroid resonator supports both single mode and multimode Raman lasing with low power thresholds.Observations of Fano and EIT-like phenomena in a packaged microresonator will enable high resolution sensors and can be used in networks where slow-light effect is needed.These results will open up new possibilities for portable,robust,and stable WGM microlasers and resonator-based sensors for applications in various environments.
