The idea of temporal solitons in optical fibres as a means to compensate for the chromatic
dispersion-induced temporal broadening of pulses via the intensity-dependent refractive …

Locking of longitudinal modes in laser cavities is the common path to generate ultrashort
pulses. In traditional multi-wavelength mode-locked lasers, the group velocities rely on …

Pure-quartic solitons (PQSs) with higher energy in short pulse width have been generated in
the mode-locked fiber laser recently, and soliton molecules have been found as a means to …

Direct generation of chirp-free solitons without external compression in normal-dispersion
fiber lasers is a long-term challenge in ultrafast optics. We demonstrate near-chirp-free …

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 …

Nonlinear optical effects are typically weak and enhancement techniques are often required
for practical applications. Here we introduce a method to enhance such effects by …

The automation of device design enabled by optimization and machine learning techniques
has been transformative for photonics. While this automation has been successful for …

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

Soliton molecules (SMs) are fundamentally important modes in nonlinear optical systems. It
is a challenge to experimentally produce SMs with the required temporal separation (TS) in …

In this paper, we study the characteristics of pure-quartic optical solitons in a nonlinear
medium having a weakly nonlocal response. We propose an nonlinear Schrödinger …
