The PhD project will use a variant of the generalised nonlinear Schrodinger equation (GNSLE) to model parametric processes, in which energy is exchanged between waves through chi(2) and chi(3) effects, and apply the model to the pulse evolution in nonlinear crystals and optical fibers. In this project we will use this model to study quasi-phase-matched (QPM) nonlinear crystals, combining the GNSLE with simulated annealing or genetic algorithms to design the QPM grating to produce (for example) extremely broadband spectra or high-purity single photons for applications in quantum technologies and fundamental studies of entanglement.
The Laser Innovation Lab at Heriot-Watt University (mccrackenlab.squarespace.com) is offering a three-year fully funded PhD position in optical modelling, where the PhD student will model nonlinear interactions in periodically poled crystals. The group is led by Dr Richard McCracken, who has a track record in developing lasers for microscopy, spectroscopy and astronomy. The group has a newly refurbished laboratory and has secured significant funding from UKRI. Access to these resources and expertise will allow a successful candidate to drive the rapid development of world–leading experimental systems and testbeds and lead to publications in high impact journals.
We are now looking for a talented individual to join us at this exciting time. A suitable applicant will have a strong undergraduate degree (or equivalent) in a physics or engineering course and be strongly motivated with the drive required to pursue three years of intensive theoretical work supported by experiment. The project will require both individual and group work and a successful candidate must be capable of operating effectively in both environments. Any candidate must have a good grounding in the theories of lasers and optics. Experience of computer programming in Matlab would is essential but knowledge of other programming languages is relevant. A relevant undergraduate project would assist in selection of a candidate.
