Query: Nanowire photonic crystal waveguides for single-atom trapping and strong
  light-matter interactions   We present a comprehensive study of dispersion-engineered nanowire photonic
crystal waveguides suitable for experiments in quantum optics and atomic
physics with optically trapped atoms. Detailed design methodology and
specifications are provided, as are the processing steps used to create silicon
nitride waveguides of low optical loss in the near-IR. Measurements of the
waveguide optical properties and power-handling capability are also presented.
