Project description

We are looking for PhD applicants with a background in physics, material sciences, chemistry, and engineering to work on a PhD project that is aiming to develop a new class of optical fibres for the next generation of high-power lasers. This project will be carried out in close collaboration with an industrial partner, a leading manufacturer of specialty optical fibres. The successful candidate will be part of a world-leading research team working on fibre fabrication and fibre lasers and amplifiers at the Optoelectronics Research Centre (ORC). The student will also have the opportunity to spend a period of time with the industrial partner.

Fibre lasers that are increasingly becoming the light source of choice for a wide range of industrial and scientific applications, have spurred the development of new types of rare-earth (i.e., Yb, Er, Tm, and Ho) doped fibres, each with a unique set of properties to match with the specific applications. Since the fibre design and material properties of the fibre core have become critical to the performance of the fibre laser, a more powerful fibre fabrication process is required than the current industry standard process, which is MCVD (Modified Chemical Vapour Deposition) - solution doping technique.

In this PhD project, we will develop novel optical fibre materials and fabrication techniques for realisation of advanced rare-earth doped fibres with tailored dopant profiles and large core, as required for the next generation of high power fibre lasers and amplifiers.

The student will have access to the world-class Zepler Institute cleanroom complex with a state-of-the-art fibre fabrication facilities. The project is also required a significant element of high power laser work. At the end of this PhD project, the student will have the opportunity to develop a wide range of skills, which include specialty optical fibre fabrication and characterization of rare-earth doped optical fibres, while acquiring knowledge on high power fibre devices.
