SIGE PHOTONIC CIRCUITS FOR MID-IR WAVELENGTH RANGE

D. MARRIS-MORINI1,2

1Centre de Nanosciences et de Nanotechnologies, CNRS, Univ. Paris-Sud, Université Paris-Saclay, 91 120 Palaiseau, France; 2L-NESS, Dipartimento di Fisica, Politecnico di Milano, Polo di Como, Via Anzani 42, 22100 Como, Italy

Ge-rich SiGe photonic circuits have been used to demonstrate a whole set of devices operating in a wide spectral range in the mid-IR. 2 octaves-supercontinuum generation was demonstrated on chip up to 13 µm, as well as optical modulation up to 11 microns wavelength.

INHIBITED-COUPLING HOLLOW-CORE FIBERS : NEW HORIZONS

F. GEROME1,2, J. OSORIO1, F. AMRANI1,2, B. DEBORD1,2, F. BENABID1,2

1GPPMM Group, XLIM Institute, CNRS UMR 7252, University of Limoges, Limoges, Fra; 2GLOphotonics, 123 Avenue Albert Thomas, Limoges, France

This communication will review our recent developments in inhibited-coupling hollow-core fibers, ranging from understanding the optical guiding mechanism to new state-of-the-art performances. These results are expected to have strong impacts in a new landscape of research and technology.



9:35 - 10:00

FLUIDS OF LIGHT IN A NONLINEAR CRYSTAL: FROM SUPERFLUIDITY TO TURBULENCE

A. ELOY, O. BOUGHDAD, M. ALBERT, P.-E. LARRE, F. MORTESSAGNE, M. BELLEC, C. MICHEL

Université Côte d'Azur, INPHYNI, France

In this talk, I will review the concept of fluids of light. I will focus on paraxial fluids of light, and present the experimental results we obtained in a photorefractive crystal, such as the observation of the superfluid transition and the appearance of quantum turbulence through the generation of vortex pairs.
