Abstract
Leveraging hybrid integration, we demonstrate dark-pulse formation at 780-nm wavelength band in integrated SiN microresonators driven by high-power AlGaAs-based chip-scale lasers. The device outputs coherent frequency combs with electronically detectable repetition rates down to 20 GHz, paving a route to efficient and compact atom-chip interfaces for spectroscopy, metrology and sensing.
