Microcomb-based information tools. In this review article, the authors have mainly presented the use of microcombs in information technology, especially to provide information (for example, opto-microwave communication, left), to obtain information (for example, LiDAR , middle) and information processing (eg, optical communication, right).

Researchers are excited about the potential of microcombs, tiny devices that produce precise time and frequency measurements. These microcombs can change the fields from fast communication, high measurements to precise atomic clocks.
Traditionally, frequency combs were large and complex, but microcombs offer a compact and powerful alternative. They achieve this through the Kerr effect or optoelectronic modulation, where light combines with different materials to produce multiple coherent waves.
Recent advances in microcomb design and control open doors for new approaches from classical to quantitative information systems.
Research review on Light explores advances in the science of microcombs, from improving performance to testing real-world conditions. The uses of microcombs are many. Acting as information carriers, they can achieve different signal generation, synchronization, and increase data transmission rates.
For information, microcombs can be used for precision spectroscopy, which enables detailed analysis of molecules and materials, and holds promise for medical imaging and astronomy. For information processing, microcombs can be an ideal light source for radio frequency processing, wireless switching, and photonic computing.
Advanced techniques for the production and control of microcombs. (Top panels) In microcomb fabrication, advanced strategies have recently been developed, such as turn-key operation based on laser injection locking, slingshot using fiber hybrid cavity, and Brillouin pumping. (Bottom panels) In processing the microcomb results, the scientists reported strategies that included electrical, mechanical and optical control.

Finally, the review discusses how to expand the functions and improve the performance of microcombs in the future, especially the possible changes in the trade-off between power and efficiency, speed and scale, stability and control.
The article outlines the research and development roadmap for microcomb technology, suggesting that microcombs can revolutionize various fields of science and industry, bringing us closer to a future shaped by precise light and information management. .
