Group IV photonics hold great potential for nonlinear applications in the near-and mid-
infrared (IR) wavelength ranges, exhibiting strong nonlinearities in bulk materials, high index …

We investigate the propagation and interaction dynamics of the optical dark bound solitons
for the defocusing Lakshmanan-Porsezian-Daniel equation, which is a physically relevant …

Ultrashort pulse generation hinges on the careful management of dispersion. Traditionally,
this has exclusively involved second-order dispersion, with higher-order dispersion treated …

Temporal optical solitons have been the subject of intense research due to their intriguing
physics and applications in ultrafast optics and supercontinuum generation. Conventional …

Solitons are wave packets that can propagate without changing shape by balancing
nonlinear effects with the effects of dispersion. In photonics, they have underpinned …

We demonstrate a peculiar mechanism for the formation of bound states of light pulses of
substantially different optical frequencies, in which pulses are strongly bound across a vast …

We numerically investigate the pulsating dynamics of pure-quartic solitons (PQSs) in a
passively mode-locked fiber laser. The bifurcation diagrams show that the PQS can alternate …

Temporal solitons are optical pulses that arise from the balance of negative group-velocity
dispersion and self-phase modulation. For decades, only quadratic dispersion was …

Bound states of optical solitons represent ideal candidates to investigate fundamental
nonlinear wave interaction principles and have been shown to exhibit intriguing analogies to …

We analyze the propagation dynamics of intense light pulses in an optical medium
exhibiting cubic–quintic nonlinearity and pure fourth-order dispersion. We show that this …
