Advancing Fourier: space-time concepts in ultrafast optics, imaging and photonic neural networks
Luc Froehly, Francois Courvoisier, Daniel Brunner +5
The concepts of Fourier optics were established in France in the 1940s by Pierre-Michel Duffieux, and laid the foundations of an extensive series of activities in the French resear…
Control of spatial four wave mixing efficiency in Bessel beams using longitudinal intensity shaping
Ismail Ouadghiri-Idrissi, John M. Dudley, Francois Courvoisier
Diffraction-free Bessel beams have attracted major interest because of their stability even in regimes of nonlinear propagation and filamentation. However, Kerr nonlinear couplings…
Akhmediev breather signatures from dispersive propagation of a periodically phase-modulated continuous wave
Ugo Andral, Bertrand Kibler, John Dudley +1
We investigate in detail the qualitative similarities between the pulse localization characteristics observed using sinusoidal phase modulation during linear propagation and those…
Chalcogenide-glass polarization-maintaining photonic crystal fiber for mid-infrared supercontinuum generation
A. N. Ghosh, M. Meneghetti, C. R. Petersen +6
In this paper, we report the design and fabrication of a highly birefringent polarization-maintaining photonic crystal fiber (PM-PCF) made from chalcogenide glass, and its applicat…
Supercontinuum Generation in Heavy-Metal Oxide Glass Based Suspended-Core Photonic Crystal Fibers
A. N. Ghosh, M. Klimczak, R. Buczynski +2
We investigate supercontinuum generation in several suspended-core soft-glass photonic crystal fibers pumped by an optical parametric oscillator tunable around 1550 nm. The fibers…
Amplitude noise and coherence degradation of femtosecond supercontinuum generation in all-normal-dispersion fibers
Etienne Genier, Patrick Bowen, Thibaut Sylvestre +3
Supercontinuum (SC) generation via femtosecond (fs) pumping in all-normal-dispersion (ANDi) fiber is predicted to offer completely coherent broadening mechanisms, potentially allow…
