AI Article Synopsis
- The study presents Raman lasing and the optical analog of electromagnetically-induced transparency (EIT) in a specialized microtoroid resonator that is embedded in a low refractive index polymer with a tapered fiber coupler.
- The microtoroid resonator enables low-threshold single and multimode Raman lasing, and exhibits Fano and EIT-like phenomena, which can enhance sensor resolution.
- These findings suggest potential advancements in developing portable and stable WGM microlasers and resonator-based sensors for a variety of practical applications.
Article Abstract
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.
