Pure-quartic solitons have gained significant attention recently due to their ability to achieve
higher energy than classical solitons for short pulse durations, leveraging the interaction …

We introduce a generalized fractional nonlinear Schrödinger (FNLS) equation for the
propagation of optical pulses in laser systems with two fractional-dispersion/diffraction terms …

An exact solitary wave solution is presented for the nonlinear Schrödinger equation
governing the propagation of pulses in optical fibers including the effects of second-, third …

In conventional temporal optical solitons the effect of the nonlinearity is balanced by that of
quadratic dispersion. In recent work we have considered solitons that balance the …

We address effects of interplay of two different fractional-diffraction terms, corresponding to
different Lé vy indices (LIs), in the framework of nonlinear Schrödinger equation (NLSE) with …

We numerically investigate the dynamics of period-doubling bifurcation to chaos in a pure-
sextic soliton (PSS) fiber laser dominated by sixth-order dispersion (SOD). By properly …

We propose a new type of bilayer dispersion-flattened waveguides that have four zero-
dispersion wavelengths. Low and flat dispersion can be achieved by using two different …

We analyze the formation of three-dimensional spatiotemporal solitons in waveguides with a
parabolic refractive index profile and pure quartic chromatic dispersion. We show, by …

We investigate a variable-coefficient fractional nonlinear Schrödinger (vc-FNLS) equation
with Wadati potential and PT-symmetric potential. We find the Lévy index can be used to …

Considering the higher-order nonlinearity is essential in a broad range of real physical
media as it significantly influences the wave dynamics in these systems. We study the …
