从理论和实验上研究了空间啁啾非线性定向耦合器中光波的自谐振动力学。我们表明，绝热通过一个弱耦合光波系统中的线性共振产生一个尖锐的阈值过渡到非线性锁相和放大到预定的幅度。这构成了光学中自共振现象的第一次观察。
We study, theoretically and experimentally, autoresonant dynamics of optical waves in a spatially chirped nonlinear directional coupler. We show that adiabatic passage through a linear resonance in a weakly coupled light-wave system yields a sharp threshold transition to nonlinear phase locking and amplification to predetermined amplitudes. This constitutes the first observation of autoresonance phenomena in optics.
