Hybrid-integrated dark-pulse microcombs towards visible light spectrum

Optics 2025-05-02 v1 Applied Physics Atomic Physics

Abstract

Leveraging hybrid integration, we demonstrate dark-pulse formation at 780-nm wavelength band in integrated Si3_3N4_4 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.
