We conduct research in strategic areas of communications and sensor technology to address the ongoing requirements of national and global industry and the demands of the information age.
Areas of research
Research is concentrated into the area of wireless systems and related applications:
- Radio system design, which involves the capacity and deployment of wireless systems.
- Air interface research, which involves the measurement and modelling of the radio channel and then the development of modulation schemes and algorithms to exploit or overcome the resulting channel characteristics.
- Radio architectures and implantation (micro)–electronics.
Telecommunications research projects
- Green wireless base-stations, based on low power transmitter electronics.
- Frequency flexible circuits, including removal of switched filters from wireless handsets, and which requires close collaboration with our microelectronics capabilities.
- Cognitive radio, which means dynamic and opportunistic access to unused spectrum. Previously this research involved TV band modems but now includes femtocell systems (i.e. very small area wireless systems).
- Body area communications involve portable sensors for measuring physical activity in the lower limbs.
Research involves the design of new integrated circuits for solving instrumentation problems and providing more efficient and effective signal processing, including:
- full-custom integrated circuits design
- semi-custom and FPGA circuits design
- MEMS/MOS sensors design.
Microelectronics research projects
- Telecommunications research, since mobile communications requires new integrated circuits to be designed, fabricated and tested.
- The development of sensors for applications in sport and health science and biomedical engineering.
Optics & photonics
Research is conducted in the areas of:
- optical fibre sensors
- optical materials
- optical fibre lasers & optical amplifiers
- imaging of photonic devices.
Optics & photonics research projects
- Optical fibre Bragg gratings are an optical filter inscribed within an optical fibre and work includes understanding the complexities of their behaviour, including sensor applications, and their application for tuning and switching applications relevant to optical networks.
- Deployment of optical fibre sensors in industrial situations, e.g. monitoring corrosion in water pipes.
- Rare-earth-doped optical fibres are vital for optical fibre lasers and optical amplifiers and improvement in their fabrication will allow enhanced performance, or better tunability. This work is enabled by the silica optical fibre fabrication facilities at UNSW with VU as a partner (funded by an ARC LIEF grant).
- Applications in biosciences and health of optical techniques include imaging using the microscope and new applications of optical fibre sensors; e.g. imaging of single muscle fibres and the assessment of compression garments.
Members of the Telecommunications, Electronics, Photonics & Sensors Research Unit continue to publish their work in a broad range of scholarly journals and in proceedings of international learned conferences.
