论文摘要
光子综合电路解决的应用程序的复杂性正在稳步上升，并且对单个组件功能，性能和足迹提出了越来越具有挑战性的需求。逆设计方法最近显示了使用全自动设计程序来满足这些需求的巨大希望，这些设计程序可以访问传统的纳米光子设计概念以外的非直觉设备布局。在这里，我们提出了一种动态二进制方法，该方法是目前最成功的逆设计算法核心的目标优先算法。我们的结果表明，与先前实现的目标第一算法相比，我们在模拟和制造设备的实验中为TE00到TE20波导模式转换器所显示的具有显着的性能优势。
The complexity of applications addressed with photonic integrated circuits is steadily rising and poses increasingly challenging demands on individual component functionality, performance and footprint. Inverse design methods have recently shown great promise to address these demands using fully automated design procedures that enable access to non-intuitive device layouts beyond conventional nanophotonic design concepts. Here we present a dynamic binarization method for the objective-first algorithm that lies at the core of the currently most successful inverse design algorithms. Our results demonstrate significant performance advantages over previous implementations of objective first algorithms, which we show for a fundamental TE00 to TE20 waveguide mode converter both in simulation and in experiments with fabricated devices.
