Abstract

We report slow light measurements in hollow core photonic crystal waveguides. We show that reshaping the slot into a comb allows increasing the confinement of light and engineering the dispersion of the waveguides. Cut-back measurements in such waveguides exhibits losses that are comparable to those of standard W1 photonic crystal waveguides in slow light regime and to those of a refractive slot waveguides in fast light regime, meanwhile the nonlinear effective area and the modal volume are strongly reduced. Such hollow core waveguides can introduce new functionalities to silicon and ultra-high nonlinearities when infiltrated by adequate materials.
