Many studies to produce the broadband comb in visible light domain is conducted, but it is challenging to get a soliton solution by large normal dispersion of materials, and making it it is difficult to become a pulse. In this study, we used silica toroid microcavity, high-Q factor microcavity, to efficiently produce third order nonlinear optical effect, and generated a comb which was equal distance from 500 nm to 523 nm by a pump light of optical communication band. We report this result which we examined about a visible comb with microcavity.
