论文摘要
在科学和技术的几个领域中，非线性光学元件在频率转换，纠缠 - 光子的产生，频率梳子的自我引用，晶体表征，传感和超短脉冲脉冲产生和表征至关重要。近年来，由于其巨大的非线性光学敏感性，它们在光子平台上的易于集成以及其2D性质，因此在该领域引起了极大的关注，因此它们放松了相匹配的约束，因此在参数非线性过程中实际上为无用的带宽提供了带宽。在这项综述中，报告和解释了该领域的最新进展，强调了它们对基本和技术方面的重要性和影响，并提供了对非原子化材料的非线性光学研究的未来研究方向的看法。
Nonlinear optics is of crucial importance in several fields of science and technology with applications in frequency conversion, entangled-photon generation, self-referencing of frequency combs, crystal characterization, sensing, and ultra-short light pulse generation and characterization. In recent years, layered materials and related heterostructures have attracted huge attention in this field, due to their huge nonlinear optical susceptibilities, their ease of integration on photonic platforms, and their 2D nature which relaxes the phase-matching constraints and thus offers a practically unlimited bandwidth for parametric nonlinear processes. In this review the most recent advances in this field, highlighting their importance and impact both for fundamental and technological aspects, are reported and explained, and an outlook on future research directions for nonlinear optics with atomically thin materials is provided.
