A microcomb developed by researchers from Chalmers University of Technology has the potential to herald significant advances in a variety of technologies, spanning metrology and optical communication. The design is based on two microresonators and is coherent, tunable, and reproducible, and has up to 10× higher net conversion efficiency than current state-of-the-art devices.
Microcombs generate a variety of uniformly distributed colors on a tiny cavity known as a microresonator. They can be used to measure or generate frequencies with extreme precision.
Researchers at Chalmers University of Technology, Sweden, present a microcomb on a chip based on two microresonators instead of one. It is a coherent, tunable, and…
