This 3-year PhD project is part of a grant funded by the Royal Society of New Zealand to study new pulse dynamics to improve the performance of current mid-IR fibre-based lasers.
This project will allow you to develop your theoretical and technical creativity. You will learn about the physics of fibre lasers, of mid-IR sources, and of supercontinuum sources that are receiving ever increasing attention around the world!
The successful applicant will participate in the research program of Dr Claude Aguergaray, Dr Miro Erkintalo and Professor Neil Broderick.
The research program focuses on the development of a new type of mid-IR supercontinuum laser. Current mid-IR supercontinuum systems are limited: either generating laser light with insufficient power spread over a wide spectral range, or generating high output power concentrated across a limited spectral region. By understanding the physics of pulse dynamic and light-matter interactions in a new class of fibres, we will explore a novel approach to constructing mid-IR SC sources with unprecedented combination of spectral coverage and power. In contrast to most contemporary designs, our source will take advantage of (1) combining pulse amplification and spectral broadening in a nonlinear amplifier to obtain a flatter and wider SC with higher output power; and (2) an architecture better suited for a cascaded SC generation approach, that together, support ultrabroad and high-power SC generation.
Through combined theoretical and experimental studies, we will explore and leverage the unique advantages of our design. The resulting knowledge will provide new research opportunities and facilitate the development of robust fibre-based mid-IR supercontinuum sources with highly anticipated academic and industrial outcomes in mid-IR lasers, frequency combs, IR spectroscopy, and medical diagnosis.
The project involves close collaborations with industrial partners Le Verre Fluoré and ALPhANOV, who are both world leaders in the fields of mid-IR fibre design, fabrication and integration.
The PhD project
The student will receive a stipend of NZ$ 27,500 per annum in addition to course fees.
The PhD candidate will be part of a supportive research group focusing on several key aspects of the development of this technology. The candidate, alongside the rest of the team, will be working on:
- Designing and optimising of the fibres used in the final amplification stage.
- Studying the pulse dynamic in the fibre-laser system using a suite of computational tools.
- Building the mode-locked oscillator as well as the amplification and the nonlinear stages.
- Writing regular summary reports to communicate our progress to our international partners.
- Improving the architecture of the system to optimise its performance.
- Prior experience working with fibres or fibre lasers is desirable but not essential.
The project is part of the wider portfolio of photonics research that is performed in the Department of Physics and in the Photon Factory at the University of Auckland, New Zealand. The Photon Factory is a multi-user, multi-disciplinary laser facility with 30+ physics, engineering, chemistry and biology students and staff. Research spans the fundamental, applied and entrepreneurial.
This fully funded PhD fellowship will be supervised by Dr Claude Aguergaray, deputy director of the Photon Factory, and co-supervised by Dr Miro Erkintalo, Senior lecturer at the Department of Physics at the University of Auckland.
The Photon Factory embraces diversity and is committed to creating an inclusive research environment in which all students and staff can succeed.
