By self-injection-locking a 1560 nm distributed feedback semiconductor laser to a high-$Q$ silicon nitride resonator, a high-coherence 780 nm second harmonic signal is generated via the photogalvanic-induced second-order nonlinearity. A record-low fr

Engineered zero-dispersion microcombs using CMOS-ready photonics

Autor: Ji, Qing-Xin, Jin, Warren, Wu, Lue, Yu, Yan, Yuan, Zhiquan, Zhang, Wei, Gao, Maodong, Li, Bohan, Wang, Heming, Xiang, Chao, Guo, Joel, Feshali, Avi, Paniccia, Mario, Ilchenko, Vladimir S., Matsko, Andrey B., Bowers, John, Vahala, Kerry

Normal group velocity dispersion (GVD) microcombs offer high comb line power and high pumping efficiency compared to bright pulse microcombs. The recent demonstration of normal GVD microcombs using CMOS-foundry-produced microresonators is an importan

Lasers with hertz-level linewidths on timescales up to seconds are critical for precision metrology, timekeeping, and manipulation of quantum systems. Such frequency stability typically relies on bulk-optic lasers and reference cavities, where increa
