标题： Frequency comb from a microresonator with engineered spectrum

摘要： 我们证明，通过改变耳语画廊模式谐振器的线宽和色散之间的比率，我们可以控制第一个生成的光梳边带与泵浦之间的自由光谱范围的数量 N。 我们观察到了具有 N=19 和 N=1 的光梳。 对于 N=1 的光梳，我们使用一个 0.4 毫米的 MgF2 谐振器，泵浦功率为 50 毫瓦，实现了超过 200 纳米的波长范围，这比之前报道的结果低了一个数量级。 显示英文摘要

摘要： We demonstrate that by varying the ratio between the linewidth and dispersion of a whispering gallery mode resonator we are able to control the number N of free spectral ranges separating the first generated comb sidebands from the pump. We observed combs with N=19 and N=1. For the comb with N=1 we have achieved a span of over 200 nm using a 0.4 mm MgF2 resonator with a pump of 50 mW, which is a factor of 10 lower than previously reported.
