    "abstract": "The demonstration of an optical fiber based probe for efficiently exciting\nthe waveguide modes of high-index contrast planar photonic crystal (PC) slabs\nis presented. Utilizing the dispersion of the PC, fiber taper waveguides formed\nfrom standard silica single-mode optical fibers are used to evanescently couple\nlight into the guided modes of a patterned silicon membrane. A coupling\nefficiency of approximately 95% is obtained between the fiber taper and a PC\nwaveguide mode suitably designed for integration with a previously studied\nultra-small mode volume high-Q PC resonant cavity [1]. The micron-scale lateral\nextent and dispersion of the fiber taper is also used as a near-field spatial\nand spectral probe to study the profile and dispersion of PC waveguide modes.\nThe mode selectivity of this wafer-scale probing technique, together with its\nhigh efficiency, suggests that it will be useful in future quantum and\nnon-linear optics experiments employing planar PCs.",
