As a universal phenomenon in nonlinear optical systems, pulsating behaviors of solitons
have attracted increasingly more investigations. While pulsating solitons and their likely …

Pure-quartic soliton (PQS) fiber lasers provide a promising avenue for exploring novel
soliton interaction dynamics and generating high-energy pulses. Here, we present the …

Solitons are self-sustaining particle-like wave packets found throughout nature. Optical
systems such as optical fibers and mode-locked lasers are relatively simple, are …

We report measurements and numerical modeling of spectral broadening and soliton
propagation regimes in silicon-on-insulator photonic wire waveguides of 3 to 4 dispersion …

Numerical simulations are used to investigate soliton-like propagation in tapered silicon
core optical fibers. The simulations are based on a realistic tapered structure with nanoscale …

Solitons are self-reinforcing localized wave packets that manifest in the major areas of
nonlinear science, from optics to biology and Bose–Einstein condensates. Recently …

We observe spectral broadening of more than 350 nm, ie, a 3/10-octave span, upon
propagation of ultrashort 1.3-μm-wavelength optical pulses in a 4.7-mm-long silicon …

Nonlinear systems with periodic variations of nonlinearity and/or dispersion occur in a
variety of physical problems and engineering applications. The mathematical concept of …

Solitons have been a subject of intense intellectual curiosity and an avenue for a plethora of
applications since they are first observed in water waves. Optical solitons, in particular, have …

In waveguide arrays the interplay of discrete diffraction and nonlinear phase modulation
evoked by either quadratic or cubic on-site nonlinearities may lead to the formation of …
