Postdoctoral Research Associate

Location: Aston University Main Campus

Contract Type: Fixed Term (36 months)

We are seeking to appoint a Postdoctoral Research Associate (PDRA) to work in the field of the Nonlinear Fourier Transform (NFT) and soliton theory and its applications in optical signal processing at the Aston Institute of Photonic Technologies (AIPT). You will join the team of Dr Auro M. Perego, Associate Professor at AIPT, and you will work under the framework of an EPSRC project “Optical Darboux Transformer for nonlinear signal processing”, also in collaboration with Dr. Mingming Tan, Research Fellow at AIPT, and with international project research partners too.

In this three-year post, you will work at state-of-the-art problem in the applications of the nonlinear Fourier Transform and namely at the development of optical filters and multiplexers for the nonlinear spectrum of an optical signal. The research project will build on recent research performed in Dr. Perego’s team about the implementation of the mathematical Darboux Transformation in the optical domain resulting in the proposal of the Optical Darboux Transformer (ODT) device to control the nonlinear Fourier spectrum. You will develop your research, in synergy with experimentalists at the AIPT, on the ODT applications in telecom, and for the control of nonlinear dynamics of light in fibre lasers and optical resonators.

The successful candidate will have completed (by the start date of the contract) a PhD degree in Photonics, Theoretical Physics, Optical Engineering, or Electronics and Electrical Engineering, and will have a proven track record in performing independent research in theoretical nonlinear fibre optics, or in soliton theory and the nonlinear Fourier Transform. Previous experience in the analytical investigation and numerical modelling of light propagation in nonlinear optical fibres, fibre lasers or resonators is required. Previous research experience in the field of the Nonlinear Fourier Transform and soliton theory and/or experimental work in nonlinear fibre optics is desirable.

For informal enquiries about this position, you can contact Dr Auro Perego, Aipt Assoc Professorial Research Fellow (a.perego1@aston.ac.uk)
