    "abstract": "We report on systematic experimental mapping of the transmission properties\nof two-dimensional silicon-on-insulator photonic crystal waveguides for a broad\nrange of hole radii, slab thicknesses and waveguide lengths for both TE and TM\npolarizations. Detailed analysis of numerous spectral features allows a direct\ncomparison of experimental data with 3D plane wave and finite-difference\ntime-domain calculations. We find, counter-intuitively, that the bandwidth for\nlow-loss propagation completely vanishes for structural parameters where the\nphotonic band gap is maximized. Our results demonstrate that, in order to\nmaximize the bandwidth of low-loss waveguiding, the hole radius must be\nsignificantly reduced. While the photonic band gap considerably narrows, the\nbandwidth of low-loss propagation in PhC waveguides is increased up to 125nm\nwith losses as low as 8$\\pm$2dB/cm.",
