Abstract

Applications in timekeeping, quantum sensing and quantum computing have sparked growing demand for high-performance photonic integrated circuit (PIC) lasers at visible and short near-infrared wavelengths between 400 nm and 1,000 nm. This Review summarizes the application needs and recent advances in such PIC lasers, focusing on low-noise, continuous-wave operation needed for many quantum technologies. We discuss the building blocks for these laser systems, including the heterogeneous and hybrid integration of gain media, low-loss PICs, external-cavity and self-injection locking schemes, and nonlinear wavelength conversion through optical harmonic generation and optical parametric oscillation processes. We review demonstrations utilizing various combinations of these elements. Finally, we consider current PIC laser performance in the context of a few example quantum technologies that require lasers at multiple wavelengths. This Review provides an overview on high-performance photonic integrated circuit lasers at visible and short near-infrared wavelengths between 400 nm and 1,000 nm, focusing on low-noise, continuous-wave operation needed for many quantum technologies.

可见光和短近红外波段的新兴集成激光技术

计时、量子传感和量子计算领域的应用引发了对波长在 400 纳米到 1000 纳米之间的可见光和近红外短波长高性能光子集成电路 (PIC) 激光器日益增长的需求。本综述总结了此类 PIC 激光器的应用需求和最新进展，重点关注许多量子技术所需的低噪声、连续波操作。我们讨论了这些激光系统的构件，包括增益介质的异质和混合集成、低损耗 PIC、外腔和自注入锁定方案，以及通过光谐波发生和光参量振荡过程实现的非线性波长转换。我们回顾了利用这些元素的各种组合进行的演示。最后，我们结合一些需要多波长激光器的量子技术实例，对当前 PIC 激光器的性能进行了分析。
