论文摘要
使用基于修改的Gross-Pitaevskii方程的模型详细研究了基于谐波光子腔的模式锁定纳米射体的Hermite-Gaussian（HG）模式的不同动力学行为。这种纳米射手显示出与腔长无关的重复速率表现出模式锁定，这是紧凑度的强大资产。关于常规激光器的差异显示出源自HG模式之间特殊的增益竞争，这是详细研究的。在有饱和吸收器的情况下，不同的机制i。 e。 Q开关，Q开关模式锁定和连续波（CW）模式锁定是在相图中隔离的，并分别描述。在具有空间分离的增益和吸收器的方案中，发现模式锁定对相强度耦合具有鲁棒性，并且可以实现。
The different dynamical behaviors of the Hermite-Gaussian (HG) modes of mode-locked nanolasers based on a harmonic photonic cavity are investigated in detail using a model based on a modified Gross-Pitaevskii Equation. Such nanolasers are shown to exhibit mode-locking with a repetition rate independent of the cavity length, which is a strong asset for compactness.The differences with respect to conventional lasers are shown to originate from the peculiar gain competition between HG modes, which is investigated in details. In the presence of a saturable absorber, the different regimes, i. e. Q-switching, Q-switched mode-locking, and continuous-wave (cw) mode locking, are isolated in a phase diagram and separately described. Mode-locking is found to be robust against phase-intensity coupling and to be achievable in a scheme with spatially separated gain and absorber.
