    "abstract": "A technique is demonstrated which efficiently transfers light between a\ntapered standard single-mode optical fiber and a high-Q, ultra-small mode\nvolume, silicon photonic crystal resonant cavity. Cavity mode quality factors\nof 47000 are measured, and a total fiber-to-cavity coupling efficiency of 44%\nis demonstrated. Using this efficient cavity input and output channel, the\nsteady-state nonlinear absorption and dispersion of the photonic crystal cavity\nis studied. Optical bistability is observed for fiber input powers as low as\n250 \\mu W, corresponding to a dropped power of 100 \\mu W and 3 fJ of stored\ncavity energy. A high-density effective free-carrier lifetime for these silicon\nphotonic crystal resonators of 0.5 ns is also estimated from power dependent\nloss and dispersion measurements.",
