IPAS Researcher Contributes to Advances in Energy-Efficient Photonic Processing
The Institute for Photonics and Advanced Sensing (IPAS) is pleased to highlight the latest publication involving Dr Lisa Haerteis, part of A/P Andy Boes鈥 Photonic Integrated Circuits team at the University of Adelaide.听
, published in APL Photonics, was carried out through the ARC Centre of Excellence in Optical Microcombs (COMBS), where Dr Haerteis is an Associate Investigator. The research explores ways to improve the efficiency and compactness of microwave photonic processors, which support high-speed communications, sensing and the growing demands of data-intensive technologies.
Working with collaborators from the University of Adelaide, RMIT University, Macquarie University, Chalmers University of Technology and the University of Twente, the team investigated the use of lithium niobate to enable more effective interaction between light and sound on a chip. This approach offers a pathway toward integrating multiple photonic functions in smaller and more energy-efficient formats.
The work presents 鈥渇loating鈥 structures that improve acousto-optic interactions. These structures can also assist in processing optical frequency combs by enabling more precise filtering and amplification of selected wavelength lines.
Congratulations to all contributors: Lisa Haerteis, Andreas Boes, Michael Steel, Arnan Mitchell, Yan Gao, Aditya Dubey, Jochen Schr枚der, Guanghui Ren, Mikolaj Schmidt and Peter Thurgood.
