虽然发明的第一个激光器在可见光下工作，但第一个片上器件在电信需求的驱动下针对近红外（IR）性能进行了优化。然而，随着集成光子学的应用范围的扩大，对波长的需求也在扩大，我们现在正在回到可见光（维斯）并推进紫外线（UV）。这种转变需要在器件设计和材料方面进行创新，并利用非线性行为来达到这些波长。这篇综述讨论了关键的非线性现象，可以使用，以及提出了几个新兴的材料系统和设备，已经达到了紫外-可见波长范围。
Although the first lasers invented operated in the visible, the first on-chip devices were optimized for near-infrared (IR) performance driven by demand in telecommunications. However, as the applications of integrated photonics has broadened, the wavelength demand has as well, and we are now returning to the visible (Vis) and pushing into the ultraviolet (UV). This shift has required innovations in device design and in materials as well as leveraging nonlinear behavior to reach these wavelengths. This review discusses the key nonlinear phenomena that can be used as well as presents several emerging material systems and devices that have reached the UV-Vis wavelength range.
