Seeing the light: high-power visible-light generation using silicate fibre. Unlike their near-infrared counterparts, visible-light-emitting lasers are inefficient and complicated, impacting their broader deployment in industry, medicine, and telecommunications. To address this, we will create a new class of laser and amplifier based on an entirely new doped silicate glass fibre that will display low background loss and resilience to photodegradation from high-power visible light. This will solve ....Seeing the light: high-power visible-light generation using silicate fibre.

To address this, we will create a new class of laser and amplifier based on an entirely new doped silicate glass fibre that will display low background loss and resilience to photodegradation from high-power visible light. This will solve one of the last important problems in fibre laser research. The primary outcome will be a series of high-power continuous-wave, ultrashort-pulse, all-fibre lasers emitting at yellow and red wavelengths, with significant benefits for space, defence, manufacturing, and human health.Read moreRead less

Universal optical transmitter for rapid prototyping and system emulation: This Project proposes an integrated, multi-user facility for the generation of extremely wide-bandwidth optical communication signals that will help to dramatically improve the data-handling capability of optical fibres and improve the energy efficiency of optical communication networks. The project will modulate the input of an advanced optical transmitter with multi-level, multi-phase signals at multi-Gb/s rates to generate 'higher-order' modulation formats at multi- terra bits per second rates including orthogonal frequency-division multiplexing (OFDM), Nyquist-wavelength-division multiplexing (WDM), regular WDM and Optical Time-Division Multiplexing (OTDM). With this transmitter the project will investigate advanced optical communications concepts including 'constellations' of phase and intensity, limitations of nonlinearity in optical fibres, signal regeneration, and all-optical routing.Read moreRead less

Stimulating light scattering in periodic structures: How slow can it go? Proof-of-concept experiments have already proven that it is possible to reduce and control the speed of light within the laboratory. This fundamental change in our understanding of light properties generated a frenzy of scientific interest and we now have a basic understanding of the physical processes involved in slowing light.

This fundamental change in our understanding of light properties generated a frenzy of scientific interest and we now have a basic understanding of the physical processes involved in slowing light. What we do not have, however, is a method of doing so that can be harnessed into useful applications outside of the lab. Our proposed approach offers a low power solution that can be readily incorporated into a myriad of engineered devices.Read moreRead less

Australia remains a world leader in enabling technologies spanning information and communication, lasers, photonic sensing and diagnostics and much more. Underpinning much of this have been key backbone facilities at UNSW and at Sydney. Optical fibre research internationally is moving in new directions and for Australia to continue its leadership role, dedicated facilities for new generation structured optical fibres, which are already impacting much more significantly than conventional fibres, must be available. The upgrade at UNSW will position Australia to continue its leadership and introduce educational and vocational training for the new industries that will depend on these core technologies.

This project aims to study new topologies for photonics-based interference mitigation filters for radioastronomy. Its significance is that it will solve, for the first time, the problem of excising RF interfering signals from within the optical signal fibre transport systems conveying radioastronomy signals from phased array antennas. These interference suppressors are key elements in removing strong unwanted man-made signals from terrestrial transmitters and satellites that coexist, and make the detection of the very weak radioastronomy signals extremely difficult. The outcome will be new high-resolution and tunable fibre-based interference suppression filters integrable with the signal transport system, which enhance the sensitivity of radioastronomy phased arrays.Read moreRead less
