PhD project SYNOX - MSCA COFUND LIGHTinPARIS Doctoral Programme

id="offer-description" class="ecl-u-type-heading-2 ecl-u-mt-none ecl-u-mb-l">Offer Description The LIGHTinPARIS programme has launched its 3rd call for PhD Fellowships with up to 6 fully funded positions starting on 1 January 2027 . The PhD projects on offer fall in the domain of the Institute for Sciences of Light (Université Paris-Saclay) covering photonics, optics, imaging, materials (chemistry), lasers, instrumentation, information, quantum technologies and more. The programme is cofunded by the European Union under Horizon Europe Marie Skłodowska-Curie Actions (MSCA) COFUND call and co-financed by Université Paris-Saclay and two non-academic partners IMAGINE OPTIC and ONERA. This is an announcement for one of the 10 PhD projects on offer. (Refer to https://euraxess.ec.europa.eu/jobs/449366 for the global announcement.) . SYNOX : Symmetry-Driven Nonlinear Optics in Hexagonal Polytype Semiconductors (Description on Web page and PDF ) . This project explores crystal-phase control to engineer material properties and unlock new functionalities. Building on a patented breakthrough enabling the growth of metastable hexagonal semiconductor thin films, we will investigate their nonlinear optical behaviour. The anisotropic hexagonal symmetry is expected to provide strong χ(2) and intrinsic birefringence, enhancing SHG and SPDC for applications in frequency conversion, optical modulation, sensing and quantum photonics. As a first demonstrator, the SYNOX project aims to develop disr
