Modulational instability, solitons and beam propagation in spatially nonlocal nonlinear media
W. Krolikowski, O. Bang, N. I. Nikolov +4
We present an overview of recent advances in the understanding of optical beams in nonlinear media with a spatially nonlocal nonlinear response. We discuss the impact of nonlocalit…

Quadratic solitons as nonlocal solitons
Nikola I. Nikolov, Dragomir Neshev, Ole Bang +1
We show that quadratic solitons are equivalent to solitons of a nonlocal Kerr medium. This provides new physical insight into the properties of quadratic solitons, often believed t…

Improving efficiency of supercontinuum generation in photonic crystal fibers by direct degenerate four-wave-mixing
N. I. Nikolov, O. Bang, A. Bjarklev
We numerically study supercontinuum (SC) generation in photonic crystal fibers pumped with low-power 30-ps pulses close to the zero dispersion wavelength 647nm. We show how the eff…
