    "Theoretical calculation, modeling and experimental measurement data for the paper \"Integrated optical isolators for broadband multi-laser operation\" accepted for publication in Nature Photonics (2026)\nAbstract: Photonic integrated circuits commonly feature visible or near-infrared lasers which are vulnerable to destabilizing back-reflections and must be protected by isolators \u2014 non-reciprocal optical components enforcing one-way light propagation. Despite recent progress, high performance isolators remain bulky off-chip components, while on-chip implementations suffer from challenging fabrication, high optical absorption, or narrow optical bandwidth. Here, we propose and experimentally demonstrate a magnet-free, intrinsically broadband traveling-wave isolator built from foundry-compatible components. Using radio-frequency electro-optic modulation to create synthetic motion across four parallel waveguides, we realize dynamic rotating destructive interference that continuously cancels backward-propagating light while leaving forward-propagating light unaffected. We reach \u224830 dB peak isolation, maintain >24 dB isolation across a 30 nm wavelength span with thermo-optic adjustment and show >20 dB isolation for two lasers simultaneously within 10 nm without any adjustment. The demonstration\u2019s 770 nm to 800 nm wavelength span covers key alkali atomic transitions, enabling on-chip laser isolation for atomic spectroscopy, laser cooling, and locking applications. Our isolator approach, applicable from the visible to telecom wavelength spectrum, offers a compelling practical solution, opening the way for fully integrated atomic clocks, quantum sensors, advanced telecommunications and tunable laser systems on a single chip."
