We report the first observation of discrete Talbot revivals in one-dimensional waveguide arrays. Unlike continuous systems where the Talbot self-imaging effect always occurs irrespective of the pattern period, in discrete configurations this process is only possible for a specific set of periodicities. Recurrence of different input periodic patterns is observed in good agreement with theory.
我们报告了在一维波导阵列中首次观察到离散的塔尔博特复兴现象。与连续系统不同，在连续系统中，无论图案周期如何，塔尔博特自成像效应总是会出现，而在离散配置中，这一过程仅在特定的一组周期性条件下才有可能发生。观察到不同输入周期图案的重现，与理论结果吻合良好。
