Nonlinear light propagation in multimode fibers

Implementation and verification of numerical solver for coupled nonlinear Schrödinger equations system in collaboration with Laboratoire Interdisciplinaire Carnot de Bourgogne. Project aims to develop more accurate numerical tools to model nonlinear propagation in multimode fibers and to investigate the control of nonlinear interactions with new fiber design. The project is co-financed by the Polish National Agency for Academic Exchange.

Main tasks:

• Perform the linear simulations for designed fibers
• Perform nonlinear simulation using MMGNLSE and UPPE models in multimode fibers
• Preparing posters for conferences, scientifics reports and papers

Works:

• Ultrashort pulse propagation and conical emission in multimode optical fibers (NAWA Meeting VPFFNI 2019)
• Normal dispersion supercontinuum reaching mid-infrared in silica microstructured optical fibers (Conference ICNP 2018)
