    The authors introduce an agile, all-fiber laser source with three frequency combs. Three EOM combs from a single laser are expanded in a tri-core nonlinear fiber, maintaining high mutual coherence. This system’s performance is showcased through a 2D four-wave mixing spectroscopy experiment.

    Multimode optical fibers can be used to observe complex intermodal processes like optical solitons. Here, Eftekhar et al. study accelerated nonlinear interaction in multimode fibers with a tapered core diameter and its effect on the temporal and spectral behavior of the multimode solitons.

    As an indirect semiconductor, silicon shows notoriously inefficient luminescence. Here, the authors utilize the Mie resonances in silicon nanoparticles to demonstrate visible white-light emission, both from free-standing spheres and particles etched on a silicon-on-insulator substrate.

    Dispersive wave emission in gas-filled hollow-core photonic crystal fibres has been possible in the visible and ultraviolet via the optical Kerr effect. Here, Köttig et al. demonstrate dispersive waves generated by an additional transient anomalous dispersion from gas ionization in the mid-infrared.

    Here, Chemnitz et al. report experimental evidence for hybrid solitons – a type of solitary wave, which emerges as a result of a strong non-instantaneous nonlinear response in CS2-filled liquid-core optical fibres, demonstrating efficient soliton-driven supercontinuum generation.

    Continuum generation in optical fibres has enabled many applications, like optical frequency combs. Here, Ohet al. demonstrate controlled dispersive-wave generation in on-chip silica waveguides, which could have a similar impact on integrated devices.

    A theoretical description of the nonlinear response of metals is complicated due to their complex electron behavior. Here, Krasavin et al. use a hydrodynamic model coupled with Maxwell's equations and demonstrate higher harmonics and supercontinuum generation from metal Archimedean spiral shapes

    Understanding how the high-energy physics of Mott-like excitations affects condensate formation is a key challenge in high-temperature superconductivity. Giannettiet al. clarify the relationship of many-body CuO2excitations and the onset of superconductivity using a new optical pump supercontinuum-probe technique.
