摘要:

我们证明了珀塞尔效应可以显著提高固态激光冷却的最大冷却功率。我们通过在掺镱二氧化硅中使用图案化槽波导结构,数值上展示了这种增强效应。增强主要来自于饱和功率密度和逃逸效率的增加,并且即使在活性材料周围结构存在寄生吸收的情况下,这种增强仍能保持。我们的结果表明,光子结构设计在光学制冷方面有新的机遇。

英文摘要:

We show that Purcell effect can lead to a substantial enhancement in the maximum cooling power for solid-state laser cooling. We numerically demonstrate such enhancement in a patterned slot-waveguide structure using ytterbium-doped silica as the active material. The enhancement arises primarily from the increase of saturation power density and the escape efficiency, and can persist in spite of the presence of parasitic absorption in the structure surrounding the active material. Our results point to a new opportunity in photonic structure design for optical refrigeration.
