We demonstrate a neural network capable of designing on-demand multiple symmetry-protected bound states in the continuum (BICs) in freeform structures with predefined symmetry. The latent representation of the freeform structures allows the tuning of the geometry in a differentiable, continuous way. We show the rich band inversion and accidental degeneracy in these freeform structures by interacting with the latent representation directly. Moreover, a high design accuracy is demonstrated for arbitrary control of multiple BIC frequencies by using a photonic property readout network to interpret the latent representation.

提出了一种基于腔辅助相互作用的远距离信息传递的方案。在该方案中,通过让一束相干光和一个囚禁在腔里面的原子进行相互作用,可以使相干光产生一个可控的相位偏移。用这种腔辅助相互作用完成了原子态和光场态之间信息的相互转移。最后我们演示了远距离信息传递方案,该方案在当前实验条件下是可行的,并且在理想条件下,成功的概率几乎为1。

为了提高聚焦光束质量,针对高功率激光驱动器的连续相位板(CPP)进行设计,改进了传统盖斯贝格-撒克斯通(G-S)算法的设计。设计基于分步分段控制相位板频谱的目标,约束初始相位的选取,保留带有目标焦斑低频信息的初始相位信息,在迭代过程中适当控制中高频信息。实验结果表明,相对于传统随机连续初始相位,改进后CPP作用下的焦斑顶部光强方均差误差(RMS)能更快地收敛到目标阈值。改进的初始相位不仅避免了G-S算法可能产生局部最优的问题,而且也能很好地应用于非对称焦斑的设计。
