论文摘要
由于其高循环强度，超高质量因子介电窃窃私语模式的谐振器使低阈值拉曼微型塑料能够发展。随后，观察到了其他与拉曼相关的现象，例如级联的刺激拉曼散射（CSR）和刺激的反stokes拉曼散射（SARS）。尽管低阈值频率转换和发电具有明确的应用，但CSR和SARS受到低拉曼增益的限制。在这项工作中，二氧化硅谐振器的表面通过有机单层修饰，从而增加了拉曼的增益。与先前的混合谐振器相比，使用子-MW输入功率观察到多达四个阶CSR，并且SARS效率通过三个数量级提高了SARS效率。
Due to their high circulating intensities, ultra-high quality factor dielectric whispering-gallery mode resonators have enabled the development of low threshold Raman microlasers. Subsequently, other Raman-related phenomena, such as cascaded stimulated Raman scattering (CSRS) and stimulated anti-Stokes Raman scattering (SARS), were observed. While low threshold frequency conversion and generation have clear applications, CSRS and SARS have been limited by the low Raman gain. In this work, the surface of a silica resonator is modified with an organic monolayer, increasing the Raman gain. Up to four orders of CSRS is observed with sub-mW input power, and the SARS efficiency is improved by three orders of magnitude compared to previous studies with hybrid resonators.
