Abstract

We demonstrate a coexistence of coherent and incoherent modes in the optical comb generated by a passively mode-locked quantum dot laser. This is experimentally achieved by means of optical linewidth, radio frequency spectrum, and optical spectrum measurements and confirmed numerically by a delay-differential equation model showing excellent agreement with the experiment. We interpret the state as a chimera state.

摘要

我们展示了被动锁模量子点激光产生的光梳中相干和非相干模式的共存。这是通过光学线宽、射频谱和光谱测量实验实现的，并通过延迟微分方程模型进行了数值验证，实验结果与理论结果吻合得非常好。我们将这种状态解释为嵌同态。
