Coupling to multi-mode waveguides with space-time shaped free-space pulses
Spencer W. Jolly, Pascal Kockaert
Guided wave optics, including most prominently fiber optics and integrated photonics, very often considers only one or very few spatial modes of the waveguides. Despite being known…
Optical modelling of single and multilayer 2D materials and heterostructures
Bruno Majérus, Luc Henrard, Pascal Kockaert
Bidimensional materials are ideally viewed as having no thickness, as their name suggests. Their optical response have been previously modelled by a purely bidimensional surface cu…
Electrodynamic models of 2D materials: can we match thin film and single sheet approaches?
Bruno Majérus, Evdokia Dremetsika, Michaël Lobet +2
The electromagnetic properties of 2D materials are modeled either as single sheets with a surface susceptibility or conductivity, or as thin films of finite thickness with an effec…
Enhanced optical Kerr effect method for a detailed characterization of the third order nonlinearity of 2D materials applied to graphene
Evdokia Dremetsika, Pascal Kockaert
Using an enhanced optically heterodyned optical Kerr effect method and a theoretical description of the interactions between an optical beam, a single layer of graphene, and its su…
Measuring the Nonlinear Refractive Index of Graphene using the Optical Kerr Effect Method
Evdokia Dremetsika, Bruno Dlubak, Simon-Pierre Gorza +8
By means of the ultrafast optical Kerr effect method coupled to optical heterodyne detection (OHD-OKE), we characterize the third order nonlinear response of graphene at telecom wa…
Impact of third order dispersion on nonlinear bifurcations in optical resonators
François Leo, Stéphane Coen, Pascal Kockaert +4
It is analytically shown that symmetry breaking, in dissipative systems, affects the nature of the bifurcation at onset of instability resulting in transitions from super to subcri…
Dispersive wave emission and supercontinuum generation in a silicon wire waveguide pumped around the 1550 nm telecommunication wavelength
François Leo, Simon-Pierre Gorza, Jassem Safioui +5
We experimentally and numerically study dispersive wave emission, soliton fission and supercontinuum generation in a silicon wire at telecommunication wavelengths. Through dispersi…
Large nonlinear Kerr effect in graphene
Han Zhang, Stephane Virally, Qiaoliang Bao +4
Under strong laser illumination, few-layer graphene exhibits both a transmittance increase due to saturable absorption and a nonlinear phase shift. Here, we unambiguously distingui…
Negative diffraction pattern dynamics in nonlinear cavities with left-handed materials
Pascal Kockaert, Philippe Tassin, Guy Van der Sande +2
We study a ring cavity filled with a slab of a right-handed material and a slab of a left-handed material. Both layers are assumed to be nonlinear Kerr media. First, we derive a mo…
