We predict the existence of a novel type of the flat-top dissipative solitonic pulses, "platicons", in microresonators with normal group velocity dispersion (GVD). We propose methods to generate these platicons from cw pump. Their duration may be altered significantly by tuning the pump frequency. The transformation of a discrete energy spectrum of dark solitons of the Lugiato-Lefever equation into a quasicontinuous spectrum of platicons is demonstrated. Generation of similar structures is also possible with bi-harmonic, phase/amplitude modulated pump or via laser injection locking.
我们预测在具有正常群速度色散(GVD)的微谐振器中存在一种新型的平顶耗散孤子脉冲,即“平板子”。我们提出了从连续波泵浦产生这些平板子的方法。通过调谐泵浦频率,它们的持续时间可能会发生显著变化。展示了将Lugiato-Lefever方程的暗孤子离散能谱转变为平板子的准连续能谱。使用双谐波、相位/幅度调制泵浦或通过激光注入锁定也可能产生类似的结构。
