The utilization of metamaterials plays a pivotal role in integrated photonics. The precise design of metamaterials enables them to finely manipulate light, resulting in an ultra-compact footprint and exceptional performance that cannot be achieved by traditional structures. The conventional methods for metamaterial design, however, encounter challenges from intricate targets. Although attempts have been made to apply inverse design to metamaterials, there is still a need for a highly intelligent, low-computation method, and easy-to-fabricate metamaterial structure. Here, we present an efficient methodology that combines metamaterials, heuristic algorithms, and machine learning to facilitate the rapid development of intricate devices. The method is used to design 1 × N power splitters with arbitrary power ratios, as an application example. Specifically, 1 × 2, 1 × 3, 1 × 4 power splitters with arbitrary ratios are fabricated and experimentally demonstrated. The application of this method in arbitrary power splitter highlights its appropriateness for the design and optimization within integrated photonics devices.
超材料的应用在集成光子学中起着关键作用。超材料的精确设计使其能够精确地操控光，从而实现超紧凑的尺寸和传统结构无法实现的卓越性能。然而，传统的超材料设计方法面临着复杂目标带来的挑战。尽管已经尝试将逆向设计应用于超材料，但仍然需要一种高度智能、低计算量且易于制造的超材料结构。在此，我们提出一种高效的方法，该方法结合了超材料、启发式算法和机器学习，以促进复杂器件的快速开发。作为应用示例，该方法用于设计具有任意功率比的1×N功率分配器。具体而言，制造并通过实验展示了具有任意比例的1×2、1×3、1×4功率分配器。该方法在任意功率分配器中的应用突出了其在集成光子学器件设计和优化方面的适用性。
