UQ Precision Technologies Translation Hub

The University of Queensland Precision Technologies Translation Hub Initiative (PTTH) seeks to enhance real-world outcomes of quantum and precision technologies research at UQ.

The Hub is a joint venture between the School of Mathematics and Physics, and the School of Information Technology and Electrical Engineering. It is directed by Professor Warwick Bowen.

The PTTH comprises UQ- and industry-based experts spanning the fields of quantum technology, photonics and electronics, healthcare and medical diagnostics, the resources sector, and the aerospace and defence industries.

Essential role

Precision technologies based on quantum and photonic science have applications in areas ranging from navigation to timing, and chemical and biological diagnostics.

Quantum effects are integral to enhancing the performance and capabilities of these technologies, with research developments currently geared towards improving sensitivity and speed, lowering energy consumption and miniaturising devices.

The PTTH focuses on the physical development of quantum and photonic technologies, and the engineering architectures required for successful field deployment.

Central to the initiative is the establishment of the Optoelectronic Integration Facility (OIF), which enables our researchers to take laboratory proof-of-principle nanotechnologies and integrate them into industry-ready prototypes.

Aims

The PTTH aims to:

create a focal point at UQ for precision-sensing research and applications
grow UQ’s ties with industry and defence
strengthen UQ’s position as an international leader in the translation of quantum nanoscience and photonics into real-world applications.

It will do this by:

developing an Optoelectronic Integration Facility (OIF) capable of developing ideas into industry-ready prototypes
providing matching start-up funds for collaborative research with industry and defence
engaging with defence and State Government individuals and organisations to establish national and state-wide precision sensing initiatives.

Optoelectronic Integration Facility

All modern technology features micro- and nano-fabricated components such as electrical logic elements and memories, nanomechanical filters and sensors, lasers and photodetectors.

The Optoelectronic Integration Facility (OIF) allows us to integrate these diverse components into application-ready technologies.

It provides capabilities for flip-chip bonding, die-bonding, housing, fibre optic pigtailing, alignment of active and passive photonic components, and wire bonding.

Location and equipment

Based in the Parnell Building (Building 7), the facility comprises interconnected rooms that are dedicated to optoelectronic and mechanical integration and packaging.

Its state-of-the-art equipment includes:

a fibre alignment and pigtailing system to connect fabricated devices to fibre optics
a die bonder to enable advanced chip-level integration processes such as flip-chip bonding, 3D packaging, chip-to-glass bonding and sensor packaging
a HEPA-filtered workstation with cleanroom class 100 laminar air flow to protect the die bonder from particulates
a critical point dryer to aid in processing fragile devices
a Vytran glass processing unit to permit specialist optical fibre tapers, lenses, terminations, splices, and couplers
a magneto-optic Kerr effect (MOKE) microscope for characterisation of magnetic surfaces and smart materials with high spatiotemporal resolution, including the capacity for elevated sample temperatures.

Wider applications

The OIF is widely applicable outside of photonic and quantum technologies, and has capabilities to integrate nanoelectronic and microfluidic systems, laser and terahertz sources, and energy harvesting devices.

The facility is available to UQ researchers and industry partners, and provides an enhanced student learning environment with strong pathways to high-skilled jobs.
