Ultra-precision Control of Optical Waves by Use of Fiber-based Frequency Combs and its Application

Optical frequency combs have opened up several new application fields not only in frequency metrology as “ultraprecise frequency ruler” but also in broad area by use of its capability for fully controlling the phase, time, and frequency information of light waves, i.e., “optical synthesizer”, with an extreme precision and wide dynamic range. In this talk, development of fiber-based frequency combs, which are the key for practical application is presented. Moreover, some of the applications of frequency combs, including precision spectroscopy for gas sensing and material characterization, distance measurement, and imaging are presented.
