Key research areas

Our team at the Integrated Photonics and Applications Centre (InPAC) is made up of six teams that work with industry to design, prototype and scale-up photonic chips to make new products.

The team has the capability to work with industry and research partners to think of new ideas, create chips, then test them in a real-world environment, all in a matter of weeks.

All our capabilities and expertise are concentrated in one location, at the RMIT Melbourne City campus, which enables us to rapidly advance photonic technologies, whilst ensuring this technology can be genuinely useful in the real world.

Key research areas

As the design team, we understand that a complete silicon photonics design framework is crucial for success. We use the industry standard IPKISS design framework from our partner Luceda Photonics for design, simulation and layout.

To ensure that designs are industry-compliant and scalable to mass manufacture, we have created and continue to develop and support a number of significant plug-ins for the IPKISS framework, including direct interfaces (and PDKs) for a range of electron-beam lithography tools, automated characterisation tools, and a comprehensive electromagnetic simulation suite, REME.

The REME simulation suite is now available within Luceda Photonics' IPKISS design flow. For further information, please contact Luceda Photonics.

For more information, please contact the InPAC Design Team Leader, Thach Nguyen.

The fabrication team focuses on the fabrication of integrated optics platforms for different applications. The platforms include silicon photonic platform (Si and SiN), and Hybrid integrated silicon photonic platform (Si + 2D materials, Si + SiN, and Si + LN). We will develop PDKs for the platforms and make them ready for end-users to realise sophisticated systems.

For more information, please contact the InPAC Fabrication Team Leader Guanghui Ren.

As the interfacing team, we understand that end-users would like to have robust and easy-to-use optical and electrical interfaces to photonic integrated circuit chips. We use different approaches for the interfacing of optical fibres to such chips, such as butt coupling and grating coupler with angle polished fibres. For electrical contacts we usually use wire bonding to connect the photonic integrated circuit chips to standard PCB boards, however custom solutions can also be investigated.

For more information, please contact the InPAC Director Arnan Mitchell.

Our team aims to use advanced modulation schemes and occupy the full optical spectrum for transmission experiments.

Future optical communication systems will have to use the full available spectral bandwidth and advanced multiplexing and modulation to achieve ultimate data capacity over a fibre link. To realistically test such links, experiments must be performed over “real-world” fibre links. The Data Comms Application team has access to a 'dark' fibre, called the Australian Lightwave Infrastructure Research Testbed (ALIRT) which links three telecommunications research laboratories (Monash University, RMIT and the University of Melbourne).

This field-deployed fibre link is used to demonstrate ultra high data transfer using the designed, fabricated and packaged photonic chips of the Integrated Photonics and Applications Centre.

Our team aims to make an impact in the future of diagnostics by offering advanced tests for the early prediction of illnesses.

Our intention is to foster the development of individually tailored therapies for more personalised medicine. The team focuses on highly multifaceted collaborative research spanning from the clinic and industry, to biochemistry, chip design, microfluidics, signal processing and bioanalytical assays among others in order to meet the needs required for the end-users. Among our aims is to operate across the translational research life cycle: development of complete point-of-care applications that lead to clinical trials, which in turn feed new hypotheses back to the laboratory.

For more information, please contact the InPAC Biomedical Applications Team Leader Cesar S. Huertas.

automated biosensor platform chip

Our team aims to deeply engage with industry and defense agencies to provide them with integrated photonic solutions for new and improved products. This is achieved by using the photonic platforms that our Centre is investigating and employing them for defence-related products. A special focus is set on energy efficiency, compact, light-weight and robust (mechanical and electro-magnetic) solutions.

For more information, please contact the InPAC Defence Applications Team Leader Andy Boes.
