Designing light sources with controllable properties at the nanoscale is a main goal in research in photonics. Harnessing disorder opens many opportunities for reducing the footprints of laser devices, enabling physical phenomena and functionalities that are not observed in traditional structures. Controlling coherent light–matter interactions in systems based on randomness, however, is challenging especially if compared to traditional lasers. Here, how to overcome these issues by using semiconductor lasers created from stealthy hyperuniform structures is shown. An on‐chip InGaN hyperuniform laser is designed and experimentally demonstrated, a new type of disordered laser with controllable transitions—ranging from lasing curve slopes, thresholds, and linewidths— from the nonlinear interplay between randomness and hidden order created via hyperuniformity. Theory and experiments show that the addition of degrees of order stabilizes the lasing dynamics via mode competition effects, arising between weak light localizations of the hyperuniform structure. The properties of the laser are independent from the cavity size or the gain material, and show very little statistical fluctuations between different random samples possessing the same randomness. These results open to on‐chip lasers that combine the advantages of classical and random lasers into a single platform.

片内超均匀激光器，用于无序系统中的可控跃迁

设计具有纳米级可控特性的光源是光子学研究的主要目标。线束紊乱为减少激光设备的占地面积提供了许多机会，从而可以实现传统结构中未发现的物理现象和功能。然而，基于随机性控制系统中的相干光-物质相互作用是一项挑战，特别是与传统激光器相比。在这里，展示了如何通过使用由隐形的超均匀结构产生的半导体激光器来克服这些问题。设计并通过实验证明了片上InGaN超均匀激光器，这种新型无序激光器具有可控的跃迁，范围从激光曲线斜率，阈值，和线宽-来自随机性和通过超均匀性创建的隐藏顺序之间的非线性相互作用。理论和实验表明，有序度的增加通过超均匀结构的弱光局部之间产生的模式竞争效应来稳定激光动力学。激光器的特性与腔尺寸或增益材料无关，并且在具有相同随机性的不同随机样本之间显示出非常小的统计波动。这些结果向片上激光器开放，这些激光器将经典激光器和随机激光器的优点结合到一个平台中。激光器的特性与腔尺寸或增益材料无关，并且在具有相同随机性的不同随机样本之间显示出非常小的统计波动。这些结果向片上激光器开放，这些激光器将经典激光器和随机激光器的优点结合到一个平台中。激光器的特性与腔尺寸或增益材料无关，并且在具有相同随机性的不同随机样本之间显示出非常小的统计波动。这些结果向片上激光器开放，这些激光器将经典激光器和随机激光器的优点结合到一个平台中。
