We implemented a photonic crystal nanofiber device by reversibly combining an optical nanofiber and a nanofabricated grating. Using the finite-difference time-domain method, we designed the system for minimal optical loss while tailoring the resonant wavelength and bandwidth of the device. Experimentally, we demonstrated that the combined system shows a strong photonic stop band in good agreement with numerical predictions. The resulting device may be used to realize strong light–matter coupling near the nanofiber surface.
