The automation of device design enabled by optimization and machine learning techniques has been transformative for photonics. While this automation has been successful for nonresonant devices, automated photonic design has remained elusive for resonant devices, key elements for on-chip communication technologies of biosensing and quantum optics, due to their highly nonconvex optimization landscapes. We propose a framework that solves this problem by mapping the design of photonic resonators to a set of nonresonant design problems. We theoretically and experimentally demonstrate this framework and show flexible dispersion engineering, a quality factor beyond 2 million on silicon-on-insulator with single-mode operation, and selective wavelength-band operation.

片上微谐振器的光子逆向设计

通过优化和机器学习技术实现的设备设计自动化已经为光子学带来了变革。虽然这种自动化对于非谐振设备来说是成功的，但对于谐振设备（生物传感和量子光学的片上通信技术的关键要素）来说，自动化光子设计仍然难以捉摸，因为它们具有高度非凸的优化环境。我们提出了一个框架，通过将光子谐振器的设计映射到一组非谐振设计问题来解决这个问题。我们在理论上和实验上证明了这个框架，并展示了灵活的色散工程，在单模操作的绝缘体上硅上的品质因数超过 200 万，以及选择性的波段操作。
