The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Low threshold photonic crystal microlasers. The aims of this project are to develop detailed finite-difference time-domain numerical models of active photonic crystal structures, and to use them to optimise the design and performance of photonic-crystal-based devices, especially micro-cavity lasers. Photonic crystal microlasers have the potential to provide very efficient and low noise laser sources in micron-sized cavities, however the simplistic structures used to realise these lasers to date ....Low threshold photonic crystal microlasers. The aims of this project are to develop detailed finite-difference time-domain numerical models of active photonic crystal structures, and to use them to optimise the design and performance of photonic-crystal-based devices, especially micro-cavity lasers. Photonic crystal microlasers have the potential to provide very efficient and low noise laser sources in micron-sized cavities, however the simplistic structures used to realise these lasers to date provide sub-optimal performance. Innovative designs with improved performance will be developed by tailoring both the optical and thermal properties of planar photonic crystal stuctures. Devices designed during this project will subsequently be fabricated at facilities in France.Read moreRead less
Studies of near-field optical emission from waveguides and photonic crystals. Advanced optical materials and photonic devices require microscopic feature sizes close to the wavelength of light, challenging the limits of conventional fabrication and characterisation techniques (often developed in parallel). With extensive expertise in near-field optical modelling, Dr Rahmani will target specific problems associated with the characterisation of actual photonic devices. This will improve device de ....Studies of near-field optical emission from waveguides and photonic crystals. Advanced optical materials and photonic devices require microscopic feature sizes close to the wavelength of light, challenging the limits of conventional fabrication and characterisation techniques (often developed in parallel). With extensive expertise in near-field optical modelling, Dr Rahmani will target specific problems associated with the characterisation of actual photonic devices. This will improve device design and fabrication, enabling the development of more efficient, compact lasers and other devices. Economic and social benefits are expected from resulting improvements in optical processing, and the potential for new jobs and industries in this field.Read moreRead less
Co-doping and transition metal doping of Gallium Nitride. Spintronics is poised to create a new paradigm in device electronics. Gallium nitride (GaN) containing trace amounts of transition metals (such as Fe,Ni) is a promising dilute magnetic semiconductor for spintronics as this material exhibits magnetic behaviour above room temperature. However, the electronic and magnetic properties of these GaN-based semiconductors have not been optimized, as yet. This project aims to establish and test a n ....Co-doping and transition metal doping of Gallium Nitride. Spintronics is poised to create a new paradigm in device electronics. Gallium nitride (GaN) containing trace amounts of transition metals (such as Fe,Ni) is a promising dilute magnetic semiconductor for spintronics as this material exhibits magnetic behaviour above room temperature. However, the electronic and magnetic properties of these GaN-based semiconductors have not been optimized, as yet. This project aims to establish and test a new growth strategy, know as the co-doping method, for the fabricate of high quality transition metal doped GaN. A broad range of complementary spectroscopic techniques will be used to refine this new fabrication technique.Read moreRead less
Relative quantum information theory. Quantum information encoded in relative degrees of freedom of multiple quantum systems offers striking advantages in communication and cryptography: it is immune to common types of noise and does not require reference systems shared between parties. This project aims to formulate a theory of relative quantum information, to develop practical information processing protocols that take advantage of relative encodings, and to propose proof-of-principle experim ....Relative quantum information theory. Quantum information encoded in relative degrees of freedom of multiple quantum systems offers striking advantages in communication and cryptography: it is immune to common types of noise and does not require reference systems shared between parties. This project aims to formulate a theory of relative quantum information, to develop practical information processing protocols that take advantage of relative encodings, and to propose proof-of-principle experiments in quantum optics that reveal these advantages. Expected outcomes include powerful communication and cryptographic protocols, a design for programmable quantum computation, and a fundamentally relative theory of quantum information connecting with other foundational fields of physics.Read moreRead less
