Title: Versatile Control of Optical Waves with Optical Frequency Combs Enables Broad Applications Beyond Frequency Metrology

Abstract: Optical frequency comb technology has been successfully used as an "ultraprecise frequency ruler," revolutionizing various fields of science and technology through absolute optical frequency measurements. However, numerous potential application fields remain unexplored for the comb. Optical frequency comb can be used as a tool for high-precision and versatile control of the full properties of optical waves as an “optical synthesizer”. It provides multi-dimensionality, ultra-wide dynamic range, together with great controllability, making it highly attractive for a broad range of applications.

In this talk, I will introduce several examples of new applications of comb, which has been conducted in our group. These include highly functional spectroscopy, imaging using optical information processing, and quantum optics, enabled by fully utilizing the comb's properties particularly optical phase controllability.
