Abstract
In this article, a passive type optical frequency comb generator and its applications are reviewed. We have developed a module of the optical frequency comb generator. The module is small, and suitable for mass production. An optical frequency counter in which the modules are used has been developed for generalpurpose frequency measuring instrument enabling the precise measurement as high as 10-10. In addition, I introduced an experiment of wave form synthesis of the optical frequency comb based on spectral line-by-line pulse shaping.
