Preface to the special topic: Nonlinear optics and devices of low-dimensional materials
2004年, 石墨烯的首次发现为具有独特光子和光电特性的二维材料的发展打开了大门. 二维材料通常被称为原子薄层材料, 其厚度可减至单层或几层. 强的层内共价和弱的层间范德瓦耳斯力是二维材料的典型特征. 不同厚度和电子结构的二维材料使其可以在紫外到太赫兹的波长范围内进行光学响应, 极大地扩展了二维材料在光子学领域的应用范围. 二维材料还具有优异的光子特性, 如泡利阻塞诱导的饱和吸收、超快的弛豫时间和高度的光学非线性, 为其在光子学领域广泛的应用奠定了基础. 由于原子层的二维材料具有机械稳定性和表面自然钝化的特点, 可无选择性地牢固地集成到其他结构中, 如平面波导、玻璃纤维、光学微腔和其他二维层状结构, 而不会出现“晶格失配”问题. 此
