Optomechanical refrigeration of electronic circuits. The project aims to apply laser light to reduce the temperature of electronic circuits. This aims to greatly suppress electronic noise, and enable a new class of technologies for future telecommunication systems. By developing new techniques to confine light, electric fields and vibrations at sub-micron scale on a silicon chip, devices such as ultralow noise amplifiers, clocks and radio frequency receivers will be realised, along with ultra-ef ....Optomechanical refrigeration of electronic circuits. The project aims to apply laser light to reduce the temperature of electronic circuits. This aims to greatly suppress electronic noise, and enable a new class of technologies for future telecommunication systems. By developing new techniques to confine light, electric fields and vibrations at sub-micron scale on a silicon chip, devices such as ultralow noise amplifiers, clocks and radio frequency receivers will be realised, along with ultra-efficient optical modulators. In future, these technologies could reduce energy consumption and improve reliability in telecommunication networks. They could improve the range of satellite communication, robustness of GPS against cosmic radiation, and performance of surveillance systems such as radar and sonar.Read moreRead less
Compact Millimeter-Wave Terminal for LEO Satellite Communications. On the basis of the cutting-edge and concept-proofed beam-steerable antenna invented by the team, this project aims at tackling the system-level challenges and developing a commercial-ready millimeter-wave satellite terminal to deal with the digital inequality facing rural and remote Australia. The proposed terminal can lead to a household-affordable price system that is compact and can be installed on a fixed/mobile platform for ....Compact Millimeter-Wave Terminal for LEO Satellite Communications. On the basis of the cutting-edge and concept-proofed beam-steerable antenna invented by the team, this project aims at tackling the system-level challenges and developing a commercial-ready millimeter-wave satellite terminal to deal with the digital inequality facing rural and remote Australia. The proposed terminal can lead to a household-affordable price system that is compact and can be installed on a fixed/mobile platform for broadband connectivity. The project will have an immediate socio-economic impact for families and small businesses located in rural areas in Australia that have poor digital access, meanwhile, it has great potential to transform the local industry partner' business into a highly profitable emerging market.Read moreRead less
A Space-Based Quantum Communications Platform using Continuous Variables. This work proposes to investigate a new space-borne platform capable of quantum communications with a terrestrial ground station. Different from existing space-borne quantum communication platforms, our new platform will be based on CV (Continuous Variable) technology and will integrate the ability to seamlessly switch to classical Free-Space Optical communications when channel conditions deem quantum communications are .... A Space-Based Quantum Communications Platform using Continuous Variables. This work proposes to investigate a new space-borne platform capable of quantum communications with a terrestrial ground station. Different from existing space-borne quantum communication platforms, our new platform will be based on CV (Continuous Variable) technology and will integrate the ability to seamlessly switch to classical Free-Space Optical communications when channel conditions deem quantum communications are too difficult. Currently no quantum satellite built on CV technology exists. Our research will produce a significant advance in an emerging technology space, and will allow Australia to take scientific leadership in an important aspect of ultra-secure communications from satellites.

Reconfigurable antennas for satellite on-the-move communications. Reconfigurable antennas for satellite on-the-move communications. This project aims to design and develop low-cost reconfigurable end-user antennas that could be integrated with low-earth-orbit satellites so regional and remote Australians can access broadband. While broadband is taking its place alongside water and electricity as essential infrastructure, people in regional Australia lack genuine broadband services. These antenna ....Reconfigurable antennas for satellite on-the-move communications. Reconfigurable antennas for satellite on-the-move communications. This project aims to design and develop low-cost reconfigurable end-user antennas that could be integrated with low-earth-orbit satellites so regional and remote Australians can access broadband. While broadband is taking its place alongside water and electricity as essential infrastructure, people in regional Australia lack genuine broadband services. These antennas are expected to give these communities reliable access to e-health services and distance education, and make their businesses more productive with access to new markets. The proposed antennas should also make broadband services available in the air, at sea, or on the move.Read moreRead less
