    Michael Withford, Macquarie University; SYdney Australia
    Presented at PICALO 2006

    We investigate the properties of tilted fibre gratings written using two techniques namely UV laser with phase mask inscription in hydrogenated fibre and point-by-point femtosecond IR inscription in non-photo-sensitised fibre. The intended application of this work is for laser light delivery from the side of an intravenous optical fibre for cauterising biological tissue in surgical procedures. Consequently, broad bandwidth ...

  • PICALO 2006 Paper #M301 (Fabrication of C-Band Resonant Structures in Rib Waveguides)

    Fabrication of C-Band Resonant Structures in Rib Waveguides
    Authors:
    Andrew Lee, Macquarie University; Sydney Australia
    Presented at PICALO 2006

    With the drive towards fabrication of "on-chip" optical technologies, there is a need to develop effective, compact, optical components. In this paper we present results on the fabrication of rib waveguide structures using SU8 which are then processed using direct laser ablation to rapidly prototype functional devices (operating in the communications band) such as Bragg filters and two dimensional photonic crystals. Laser ablation allows excellent control of the positioning and depth of ablated features within the waveguide, allowing us to tailor the r...

    Michael J. Withford, Macquarie University; Sydney Australia
    Presented at PICALO 2006

    With the goal of fabricating photonic devices for optical networking applications, significant attention has recently been directed to the use of femtosecond laser pulses for inscribing optical components inside transparent materials. In 1996 it was shown that tightly focused infrared femtosecond laser pulses induced a refractive index chan...

  • PICALO 2006 Paper #M304 (Fabrication of Periodic, Resonant Features in Optical Fibres Using a CO2 Laser Micro-tapering System)

    Fabrication of Periodic, Resonant Features in Optical Fibres Using a CO2 Laser Micro-tapering System
    Authors:
    Douglas Little, Macquarie University; Sydney Australia

    Michael Withford, Macquarie University; Sydney Australia
    Presented at PICALO 2006

    We report on novel devices fabricated using an optical fibre micro-tapering facility based on a CO2 laser and high precision translation stages, all of which are computer controlled. The use of a laser to heat the fibre is advantageous over standard flame-tapering systems as it allows greater control over the tapering parameters, namely the size of the irradiated zone, th...

    Presented at PICALO 2006

    Since the publications of E. Yablonovitch and S. John on the optical properties of periodic, dielectric structures in the year 1987 there have been intensive research efforts related to the design and new methods for the fabrication of functional photonic crystal devices. Many of these investigations addressed the realization of high refractive index structures possessing a complete photonic band g...
