WALL-IN project CNRS-UoA
4 January 2021

New partnership between CNRS and The University of Auckland. The WALL-IN project (confining walls-of-Light in nonlinear Kerr resonators) is a 5-years international research action between the CNRS and The University of Auckland funded by the CNRS and focused on the study of nonlinear dynamics occurring in optical Kerr resonators. The aim is to fund some short and long stays in both Universities for researchers and students. In this framework, Julien will stay in Auckland until next August 2021.

Invited talk in CLEO US
5 March 2019

Julien gets an invited talk at CLEO US dealing with our results on the Multiple Modal and Wavelength Conversion Process of a 10-Gbit/s Signal in a 6-LP-Mode Fiber. This work was done in collaboration with Prysmian group and the University of Lille.
Julien used the 6-LP mode fiber from Prysmian group as well as spatial multiplexer/demultiplexer from cailabs.
