Spontaneous optical skyrmion generation by frequency doubling in underdense plasmas
Marcos G. Barriopedro, Eduardo Oliva, Miguel A. Porras
Optical skyrmions have been widely explored in recent years. Among them, Stokes skyrmions require sophisticated wave engineering or photonic devices for their generation. We show t…
Non-diffracting meronic spin defects of light
Nilo Mata-Cervera, Miguel A. Porras, Yijie Shen
Optical vortices are singularity lines where the light field intensity vanishes and its phase is undefined. These threads of darkness are adorned by Gauss's law as lines of pure lo…
Gouy phase-assisted Zeno effect for protecting light structure in random media
Nilo Mata-Cervera, Anton N. Vetlugin, Cesare Soci +2
Identifying physical mechanisms that protect the information carried by various forms of structured light is one of the cornerstones of today's classical and quantum communications…
Diffraction-free natural optical skyrmions and their subwavelength confinement around vortices
Nilo Mata-Cervera, Deepak K. Sharma, Ramon Paniagua-Dominguez +2
Diffraction causes waves to spread out as they propagate freely. The tighter the lateral confinement, the faster the spreading. Past research on how to suppress diffraction has bee…
Optical Skyrmions of Vortex Darkness
Nilo Mata-Cervera, Deepak K. Sharma, Yijie Shen +2
We disclose the existence of a type of optical skyrmion, Gauss-Stokes (GS) skyrmions, that is naturally present in an optical vortex around its phase singularity. Contrary to previ…
Observation of helical pulses
Ren Wang, Shuai Shi, Zeyi Zhang +4
Ultrafast spatiotemporal vortex pulses constitute a category within spatiotemporal topological waves. Nevertheless, the experimental realization of helical pulses single or few cyc…
