High Q optical microcavities are important in nonlinear optical devices and cavity quantum electrodynamics (cavity QED) systems.We have developed a high Q optical nanofiber cavity by combining a fiber Bragg grating and optical nanofiber and applied it to cavity QED.On the other hand, 1D photonic crystal cavities on optical nanofibers (ONF-PhC cavities) achieved a small mode volume, but the Q was only about 10⁶.In this study, we fabricated an ONF-PhC cavity with a Q exceeding 10⁷ and measured its nonlinear optical response.
