摘要:

片上相干激光源对于光子集成电路的未来至关重要,然而材料质量、器件几何结构与性能指标之间的复杂相互作用一直阻碍着其进展。我们将高通量表征、统计分析、实验设计与多目标贝叶斯优化相结合,以加速低阈值、高成品率、可在通信波长室温下工作的III-V族微环激光器的设计过程。我们展示了与专家设计的配置相比,阈值降低了1.6倍,实现了100%的激射成品率,发射波长位于O波段,中值阈值低至33μJ cm⁻²脉冲⁻¹。

英文摘要:

On-chip coherent laser sources are crucial for the future of photonic integrated circuits, yet progress has been hindered by the complex interplay between material quality, device geometry, and performance metrics. We combine high-throughput characterization, statistical analysis, experimental design, and multi-objective Bayesian optimization to accelerate the design process for low-threshold, high-yield III-V microring lasers with room-temperature operation at communication wavelengths. We demonstrate a 1.6$\times$ reduction in threshold over expert-designed configurations, achieving a 100% lasing yield that emits within the O-band with a median threshold as low as 33$μ$J cm$^{-2}$ pulse$^{-1}$.
