ZORRO: Zirconium oxide resonators for all-in-one Raman and whispering-gallery-mode optical sensing
Articolo
Data di Pubblicazione:
2017
Abstract:
We report the observation of whispering-gallery modes in 2 lm-sized SiO2/ZrO2 core/shell beads utilized as all-dielectric Raman enhancers. This allows us to achieve simultaneous optical and Raman ultrasensitive detection with a single spectral analysis. This opportunity opens exciting perspectives for the multimodal chemical sensing and fabrication of optical fiber devices.
