We report the observation of whispering-gallery modes in 2 μm-sized SiO/ZrO 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.
我们报告了在用作全介质拉曼增强器的2微米大小的SiO/ZrO核壳微珠中观察到回音壁模式。这使我们能够通过单次光谱分析实现光学和拉曼超灵敏检测。这一机遇为多模态化学传感和光纤器件制造开启了令人兴奋的前景。
