Job Details

This project aims to develop novel ultra-wideband Bi-doped fibre amplifiers and lasers covering the wavelength spans 1150 – 1500nm and 1625 – 1750nm where no silica based rare earth doped fibre amplifier exists. The first challenge to achieving this relates to fibre fabrication and determining understanding the associated detailed spectroscopic characteristics, including developing an understanding of the valence state of the Bi-ion that contributes to the near-infrared emission and establishing the exact absorption and transmission spectra of the active fibres. This will lead to optimised fibre designs aimed at tailoring the gain bandwidth based on different pumping schemes and ultimately the realisation of a variety of compact, high performance active fibre amplifiers. If successful, this work will yield a >4-times enhancement in the transmission capacity of single mode fibre as used in today’s transmission systems. In addition, the broad gain spectra of bismuth (> 400nm) is suitable for the development of short pulse fibre lasers through the adoption of suitable mode locking techniques.

Two fully-funded PhD positions, sponsored by II-VI foundation (USA), are available for UK and EU applicants. We are seeking students with a background in physics/chemistry/engineering/materials science and a strong interest in optical fibre technology and/or laser technology to work on this ambitious project. A generous stipend of £19,300 per annum will be available for highly motivated students.

To informally discuss further about the project, or to arrange a visit to meet us and see our cutting edge fabrication facilities, then please contact Prof David Richardson (djr@orc.soton.ac.uk) or Prof Jayanta Sahu (jks@orc.soton.ac.uk).
