mm-Wave photonics in crystals – This project aims to create a new laser-based approach for generating frequencies of increased spectral purity and wider frequency range. This is significant as forefront areas such as quantum sensing and wireless communications that rely on ultra-precise measurement and ultra-sensitive detection require more adaptable, higher-purity, frequency sources. This project uses the enhanced and diversified material properties of crystals to create new designs capable of breaking through barriers in spectral purity and power, and performance aspects critical in applications. The aim is to investigate a novel reconfigurable device that enables single line output for ultra-narrow linewidth applications, or by reconfiguring to produce multiple line output for microwave and millimetre wave applications.

Salary level includes base tax-free scholarships with top-ups (up to AUD$48,000, tax-free). Domestic and international students are welcome to apply.

These projects would suit students interested in building novel experiments and hands-on optical techniques. The projects involve handling high power laser beams, developing table-top laser arrangements and the development of frequency noise diagnostics. They will also include the development of a model simulation to support optimization and to understand performance limits. These give plenty of scope to allow student input on directions, industry participation and intellectual property creation.

The experiments are hosted within the MQ Photonics Research Centre. Students will benefit from a network involving the Sydney Quantum Academy and the Macquarie Centre for Quantum Engineering, as well as a large infrastructure in the areas of optics, photonics and lasers. We focus on developing industry linkages in the early stages of the project to increase opportunities for students to tackle real-world challenges, grow their network beyond academia and industry-embedding parts of their project. Industry supported top-ups are available.

The Macquarie University campus is located on the northside of Sydney, approximately 35 min from the city centre by Metro. The leafy campus features modern facilities including outdoor and indoor heated swimming pools; sporting fields and more. Sydney is a bustling cosmopolitan city that is blessed to sit amongst national parks, pristine beaches and nearby mountains. For more details on campus and city life see:
