We explore the scope for engineering dispersion in whispering gallery mode silica microbubbles for nonlinear applications, such as optical frequency comb generation. In particular, the zero dispersion wavelength is shown to be highly tunable by changing the thickness of the shell. Using a small diameter and small wall thickness, dispersion equalization within the visible is predicted. This opens up the possibility of realizing visible frequency combs for a range of different applications.
我们探索了在回音壁模式二氧化硅微泡中进行工程色散以用于非线性应用（如产生光学频率梳）的范围。特别是，通过改变壳层厚度，零色散波长显示出高度可调性。利用小直径和小壁厚，预计在可见光范围内可实现色散均衡。这为实现适用于一系列不同应用的可见频率梳开辟了可能性。
