Abstract

This is a PhD Research project in Physics.

Fraser is working to develop photonic solutions to modal noise in high resolution spectroscopy. At the core of his research is the application of multicore fibre "photonic lanterns" that facilitate the efficient coupling of multimode light to an array of single modes. Once in the single mode regime, the single modes can be manipulated using components such as ultrafast laser inscribed 3D waveguides structures to create a diffraction-limited slit. Since this component is expected to distribute modal noise effects along the slit, rather than across it, it is anticipated that such approaches will enable mode-noise free spectroscopy. Such technologies are of high interest to both academia (e.g. astronomy) and also industry (e.g. metrology). As a result, this Renishaw-supported project is aimed at developing photonic approaches to mode-noise-free spectroscopy for both science- and industry-related applications. During the project, the student will gain experience in the following techniques..
1. Fibre-optic transitions
2. Spectrograph design
3. Photonic Instrumentation
4. Image processing
5. Waveguide modelling
6. Waveguide writing using ultrafast laser pulses
