N2 - On-chip coherent laser sources are crucial to enable 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× reduction in threshold over expert-designed configurations, achieving a 100 % lasing yield over 80 rings that emit within the O-band with a median threshold as low as 33 µJ cm−2 pulse−1
