Optical temporal solitons, arising from self-phase modulation and negative quadratic (β 2)
dispersion, are Galilean invariant, and therefore their properties do not depend on their …

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

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 …

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 …

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 numerically solve a generalized nonlinear Schrödinger equation and find a family of
pure-quartic solitons (PQSs), existing through a balance of positive Kerr nonlinearity and …

Solitary waves in materials with a cascaded χ^(2): χ^(2) nonlinearity are investigated, and
the implications of the robustness hypothesis for these solitary waves are discussed. Both …

We present an overview of nonlinear phenomena related to optical quadratic solitons—
intrinsically multi-component localized states of light, which can exist in media without …

We show theoretically that stable dark solitons can exist in the presence of pure quartic
dispersion, and also in the presence of both quadratic and quartic dispersive effects …

Temporal solitons in quadratic nonlinear media with normal second-harmonic dispersion
are studied theoretically. The variational approximation and direct simulations reveal the …
