Description: Researchers demonstrated single-pulse all-optical switching (AOS) of magnetization in a silicon nitride ($ ext{Si}_3 ext{N}_4$) photonic integrated circuit. Using femtosecond laser pulses, they achieved deterministic switching in a Co/Gd Hall cross, showing up to 90% contrast on small devices. This work establishes a foundation for scalable, energy-efficient spintronic-photonic platforms.
