PhD Scholarship Period doubling, chaos and stability in mode-locked lasers

The dynamics of light propagation in a mode-locked laser is a treasure trove of interesting effects from stable pulsing (producing the world’s most accurate clocks) to chaotic behaviour with applications in cryptography and everything in between. In this project we will use a variety of mathematical models to study the behaviour of both semiconductor and fibre lasers to look at the properties of both. This work will involve working closely with experimentalists in Paris, Zurich and Auckland and is expected to lead to optimised designs that can be demonstrated experimentally.

PhD Scholarship Coupled cavity dynamics in photonic crystals at The Dodd-Walls Centre

Passively driven optical cavities, such as micro-resonators, fibre loops or photonic crystal cavities all display a wide range of dynamical behaviour due to the interplay of nonlinearity, loss and linear coupling. In this project we will model the behaviour of two coupled cavities passively driven by a single source, demonstrating the existence of chaotic dynamics as well as stable pulsing regimes. This work will be performed in collaboration with experimentalists in Paris. It's goals are a new understanding of their current experiments and potentially leading the way for new experiments in quantum chaos.

Both projects will be supervised by Professors Bernd Krauskopf and Neil Broderick at the Dodd-Walls Centre. The funding for this project will be in the form of an annual stipend of NZ$27,000 (tax free), plus fees, for three years. Additional funds are available towards expenses such as conference travel. These Scholarships at the University of Auckland will be awarded competitively. Applications are encouraged immediately. The exact start date in late 2017 or early 2018 will be agreed with the successful candidate.

Informal enquiries and expressions of interest should be addressed to b.krauskopf@auckland.ac.nz and/or n.broderick@auckland.ac.nz. For general information about PhD scholarships and the application process, visit www.math.auckland.ac.nz/future-postgraduates or email phdadvice@math.auckland.ac.nz.

The Dodd-Walls Centre for Photonic and Quantum Technologies was established in 2014 as a multi-institution and multidisciplinary centre of research excellence by the NZ government. Our goal is to pursue world-leading research into all aspects of light-matter interactions from the fundamentals of quantum information theory to sensor development for NZ industry. The University of Auckland as the major research University within NZ is playing a major role in the DWC. This project will be part of the theme Sources and Components at The University of Auckland.
