Although we assume to initially couple the light into only one high spatial mode of the capillary, we have identified that the beam can propagate as a new type of multi-mode solitonic structure, the spatiotemporal-dressed soliton, which consists of a mixture of spatial modes in which one has most of the energy while the rest of them, with small contributions, module (dress) the propagation of the main spatial mode. As a consequence of such behavior, we observe a clean self-compression process, obtaining a pulse in the single-cycle limit, accompanied by a giant blue dispersive wave and a new type of multi-mode dispersive wave that appears in the mid-IR region. eng info:eu-repo/semantics/openAccess Hollow core fibers Nonlinear effects Nonlinear optical fibers Nonlinear optics Optical fibers Temporal solitons Spatiotemporal-dressed optical solitons in hollow-core capillaries info:eu-repo/semantics/article
