New nonlinear photonic waveguides
Photonic waveguides for telecommunication applications
main collaborators : Dr. Kamal Hammani, Dr. Manon Lamy, Pr. Jean-Claude Weeber
main period : 2015-2019
During the PhD work of Manon Lamy, we had the opportunity to take part in the characterization of new optical waveguides of high-speed transmissions in the conventionnal C-band. We also investigated the new wavelength region around 2 µm.
We were able to validate the use of various waveguides designed and manufactured at the ICB lab or in other labs. Some of those components were including innovative grating structures in order to enhance the coupling efficiency and we provided the first demonstration of telecom signal transmission in TiO2 waveguides.

Photonic waveguides for non-linear applications
main collaborators : Dr. Kamal Hammani, Dr. Manon Lamy, Dr. Bart Kuyken
main period : 2015-2019
We have investigated the potential use of new integrated photonic waveguides for nonlinear effects. Different materials were studied such as TiO2, silicon waveguides, Si-rich Si nitride waveguides operating around 1550 nm or around 2 µm.
In that context, we demonstrated the first generation of an octave spanning supercontinuum in TiO2 waveguide. This waveguide designed and fabricated at ICB was pumped in the femtosecond regime at 1550 nm.
We also confirmed the possibility to achieve efficient wavelength conversion around 2 µm in Si and SiRN waveguides.

Dispersion varying fibers
main collaborators : Fang Feng, Dr. Alexei Sysoliatin, Pr. Stefan Wabnitz
main period : 2007-2015
We studied different kinds of dispersion varying fibers provided by the Fiber Optics Research Center (FORC, Russia).
With dispersion decreasing fibers with normal dispersion, we carried out the first demonstration of self-similar generation and its combination with distributed Raman amplification.
With dispersion oscillating fibers, we investigated several new nonlinear dynamics, both experimentally, numerically and theoretically.

main period : 2011-2016
During the PhD of Serkan Kaya, we were involved in the characterization of various plasmonic devices in order to quantify their temporal response to ultrafast phenomena (picosecond of nanosecond ranges).
Transmission experiments were carried out and thermo-optical properties of different designs were investigated.
