  ABSTRACT: We report on recent progress in the conception and fabrication of hollow-core photonic crystal fibers. To illustrate their strong potential, experiments dedicated to the delivery and the manipulation of high-power ultrashort pulses are developed. Then, the limitations principally dictated by the nature of guidance of these fibers are highlighted and solutions proposed. Finally, recent works based on particular HC-PCF guiding broad optical transmission bands with relative low-loss are presented and their opportunities discussed.

  ABSTRACT: We report smooth and broad continuum generation using a compact femtosecond Ti:Sapphire laser as a pump source and a tapered photonic crystal fibre as a nonlinear element. Spectral output is optimized for use in optical coherence tomography, providing a maximum longitudinal resolution of 1.5 microm in free space at 809 nm centre wavelength without use of additional spectral filtering.
