Synthetic-reflection self-injection-locked microcombs

Abstract

Laser-driven microresonators have enabled chip-integrated light sources with unique properties, including the self-organized formation of ultrashort soliton pulses and frequency combs (microcombs). While poised to impact major photonic applications, such as spectroscopy, sensing and optical data processing, microcombs still necessitate complex scientific equipment to achieve and maintain suitable single-pulse operation. Here, to address this challenge, we demonstrate microresonators with programmable synthetic reflection providing an injection-feedback to the driving laser. When designed appropriately, synthetic reflection enables deterministic access to self-injection-locked microcombs operating exclusively in the single-soliton regime. These results provide a route to easily-operable microcombs for portable sensors, autonomous navigation, or extreme-bandwidth data processing. The novel concept of synthetic reflection may also be generalized to other integrated photonic systems.
