Our activities


The nonlinear photonics group focuses on research and development of nonlinear photonics devices for applications such as optical communications, instrumentation and biomedicine.

Nonlinear optics is the most versatile approach for the processing of light signals, by enabling a modification of the properties of light interacting with matter and interacting with other light signals.

Originally demanding high-power lasers and long interaction lengths, nonlinear optics can now be achieved with low power light sources and small footprint devices, owing to the progress in highly nonlinear fibers and waveguides such as those developed in our laboratories.

Our research in nonlinear optics includes the fabrication of nonlinear signal processing devices such as laser sources, wavelength converters and optical communication devices as well as the fabrication of optimized nonlinear media to be used as compact and low power consumption engines of nonlinearity.
