    "abstract": "We demonstrate a new class of hollow-core Bragg fibers that are composed of\nconcentric cylindrical silica rings separated by nanoscale support bridges. We\ntheoretically predict and experimentally observe hollow-core confinement over\nan octave frequency range. The bandwidth of bandgap guiding in this new class\nof Bragg fibers exceeds that of other hollow-core fibers reported in the\nliterature. With only three rings of silica cladding layers, these Bragg fibers\nachieve propagation loss of the order of 1 dB/m.",
