Query: Photonic crystal nanofiber using an external grating   We implement a photonic crystal nanofiber device by reversibly combining an
optical nanofiber and a nanofabricated grating. Using the finite-difference
time-domain method, we design the system for minimal optical loss while
tailoring the resonant wavelength and bandwidth of the device. Experimentally
we demonstrate 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 to the nanofiber surface.
