Offer Description
The aim of the project is to develop powerful and practical soliton microcombs based on the silicon nitride (SiN), Aluminium nitride (AlN) or lithium niobate (LiNbO3 ) platforms. Our dual-mode scheme shows great promise for developing octave- spanning combs with high efficiency pumped by high power semiconductor lasers [1]. This project is co-funded by EPSRC (UK) and Science Foundation Ireland (SFI). The candidate will be based in the group of Professor John Donegan in the School of Physics, Trinity College Dublin, but will also collaborate closely with Prof. Dmitry Skryabin of Bath University, a world-leading expert on modelling of soliton dynamics in microresonators.
Interested applicants should submit a CV highlighting relevant experience, a full list of publications and a letter explaining your motivation for this position. The documents should be sent with subject heading “post-doc SiN” to Prof. John Donegan by email at [email protected] .

Skills/Qualifications
Requirements: A PhD in Physics or Engineering is an essential requirement. Only those with experience in microcomb generation in resonators or fiber systems will be considered. They should also have laboratory experience of building and testing optical characterization systems. The ideal candidate will have demonstrated expertise in photonic simulations using Lumerical FDTD, COMSOL or equivalent software. Excellent written and oral communication skills are also essential. It would be advantageous to have demonstrated leadership skills.
Specific Requirements
The candidate will require skills in optical design, characterization of optical microresonators, in particular pumping such devices for microcombs and ultimately soliton generation. The research objectives are 1) Design, and characterise SiN microresonators supporting dual-modes providing optimized soliton-existence range and octave-wide combs. 2) Through the development of AlN and LiNbO3 microresonators possessing second-order optical nonlinearity, extend comb spectral coverage and achieve effective soliton control with enhanced nonlinear and electro-optic effects. 3) Demonstrate the SiN and AlN comb sources with > 1mW per line and bandwidth greater than 20 nm. We will work closely with the Bath team on the design and modelling of such resonators and look for novel effects including soliton crystals while seeking designs for high efficiency. Develop applications of such microcomb sources for ultra-broadband WDM communications, LiDAR and sensing.
