分析了高Q微腔中级联四波混频的过程，表明在适当的腔模色散条件下，可以产生宽带频率梳。我们实验证明了总带宽大于200 nm的高Q硅微球在反常群速度色散区的宽带级联四波混频参数振荡。
We analyze the process of cascaded four-wave mixing in a high-Q microcavity and show that under conditions of suitable cavity-mode dispersion, broadband frequency combs can be generated. We experimentally demonstrate broadband, cascaded four-wave mixing parametric oscillation in the anomalous group-velocity dispersion regime of a high-Q silica microsphere with an overall bandwidth greater than 200 nm.
