This week’s Image of the week is taken from a recent JPhysB paper by researchers from Shunde Polytechnic, China, Texas A&M University at Qatar, Qatar and Xi’an Jiaotong University, China in which they study Airy-Bessel light bullets. Light bullets are pulses of electromagnetic energy that can travel through a medium and keep their spatiotemporal shape, where diffraction and other effects would usually cause them to spread out.
Wei-Ping Zhong et al present self-decelerating Airy-Bessel light bullets as solutions of the 3D Schrödinger equation. They show the behavior of the self-decelerating pulses of light with their profiles in time and space. They find that they can take the form of disk-shaped rings, vortex rings, azimuthally-modulated rings, and necklace structures (as shown above).
