Flexibility in engineering holey structures and controlling the wave guiding properties in
photonic crystal fibers (PCFs) has enabled a wide variety of PCF-based plasmonic …

We show that the higher-order soliton evolution can be considerably affected by the relative
positions of the zero-nonlinearity wavelength (ZNW) and zero-dispersion wavelength (ZDW) …

Theoretical consideration of the propagation of femtosecond Gaussian pulses in a one-
dimensional composite medium, consisting of alternating self-focusing and self-defocusing …

This review provides a detailed discussion of both the mathematical treatment and the
impact of a frequency-dependent Kerr nonlinearity on the propagation of short pulses in …

We study numerically the evolution of ultrashort pulses in passive uniform photonic-crystal
fibers designed such that their nonlinear Kerr coefficient γ varies considerably with …

In recent times, materials exhibiting frequency-dependent optical nonlinearities, such as
nanoparticle-doped glasses and other metamaterials, have gathered significant interest. The …

We present a detailed overview of the physics of two-color soliton molecules in nonlinear
waveguides, ie bound states of localized optical pulses which are held together due to an …

Photonic crystal fibers doped with silver nanoparticles exhibit a Kerr nonlinearity that can be
positive or negative depending on the input wavelength and which vanishes at a specific …

We study incoherently coupled two-frequency pulse compounds in waveguides with single
zero-dispersion and zero-nonlinearity points. In such waveguides, supported by a negative …

Pulse propagation in nonlinear waveguides is most frequently modeled by resorting to the
generalized nonlinear Schrödinger equation (GNLSE). In recent times, exciting new …
