| Outline of Final Research Achievements |
To address the need for real-time data processing and feedback from sensors in the era of Society 5.0, this research aimed to develop high-functionality and portable light sources (microresonator frequency comb: microcomb) by advancing optical microresonator technologies. The study successfully developed optical frequency comb sources using high-Q magnesium fluoride whispering gallery mode resonators and silicon nitride microrings. Furthermore, we conducted foundational research on background-free, ultrahigh-repetition pulse light sources using erbium-doped optical microresonators. This development holds promise for applications in various fields, such as communications, sensors, medical, and precision machining. Additionally, we established a consortium to promote microcomb research to the industry.
