From quantum computing to biomedical implants and electronics, learn about some听of our听research projects听within听the听Microsystems Research Group below:听

MEMS based听optical听cross-switch (OXC)听听
This project is about the development of an all-optical cross switch using MEMS technology for applications in provisioning and restoration of optical communication networks. Whilst many silica fiber-based听optical switches have been reported, this development uniquely addresses the monolithic integration of the switch within the fabric of planar silica waveguides on a silicon substrate.听听
This is facilitated by the successful development of two novel and critical components:听听
- A听low voltage bistable actuation mechanism for out-of-plane actuation of the micromirror which is monolithically听inegrated听onto the actuator.听听
- A pair of planar silica听focussing听element for low loss free-space propagation within the switch.听

Optical interconnect for 3D integration of听integrated听circuits听听
This project is about the development of optical interconnects for 3D integration. In 3D integration of integrated circuits, the silicon chips are stacked on top of each other. Aggressive dimensional scaling has brought us into the 32nm node. 3D integration will allow the era听gigascale听integration to meet the听evergrowing听demands of greater functionality in integrated circuit systems.听

Integrated quantum computer devices听听
Prof. Andrew听Dzurak听leads听several听research projects within the Integrated Quantum Computer Devices Program of the Centre for Quantum Computer Technology (CQCT). The program provides engineering听design,听modelling and nanofabrication of fully configured听Si:P听qubits and associated pathway devices, making extensive use of the Semiconductor Nanofabrication Facility (SNF).听

Quantum measurement听听
Professor Andrea Morello manages听the听Quantum Measurement &听Control听Chip Program within the Centre for Quantum Computer Technology (CQCT).听.听The research projects within this program focus on the coherent control and readout of a single-P-atom electron spin qubits in silicon.听Throughout 2009, a new donor听spin听qubit听architecture developed within the Centre was investigated in depth, achieving one of the most important milestones in solid-state spin qubits research-the single-shot readout of an electron spin.听

Development of RF MEMS technology for modern wireless communications systems听听
In modern wireless communication systems, information data transmission听must听be able to handle multiple frequency bands and to provide multiple听channels听for different signals. The solution is to combine听the听increase in bandwidth (ultra-wide bandwidth) and speed, thus develop technologies for the transceiver听architecture.听听
This听requires new technologies and fabrication processes for circuits, devices and components, as well as the development of new materials.听Our听focus听is听to develop RF MEMS technology for reconfigurable communication systems with multifunctional capabilities.听

Ultra-low temperature听electronics听听
This research is motivated by the need for controlling and听observing听spin-based silicon quantum computing processors in future quantum computers. Such quantum computing processors will be operating at temperatures below 1K. To facilitate the quantum processor control, conventional electric circuits are required operating at temperatures below 4.2K.听

Circuits for biomedical听implants听听
This research is motivated by the strict power and reliability requirements of electronic implants and capsules, such as cochlear implants, vision prostheses and wireless endoscope. The available power in such systems is very听limited:听either due to limits on safe听transcutaneous听power transfer or the limited capacity of installed batteries.听The听focus听of this research is to reduce the power dissipation of the required circuit functions.听
