    "abstract": "The efficiency of evanescent coupling between a silica optical fiber taper\nand a silicon photonic crystal waveguide is studied. A high reflectivity mirror\non the end of the photonic crystal waveguide is used to recollect, in the\nbackwards propagating fiber mode, the optical power that is initially coupled\ninto the photonic crystal waveguide. An outcoupled power in the backward\npropagating fiber mode of 88% of the input power is measured, corresponding to\na lower bound on the coupler efficiency of 94%.",
