Demonstration of space-time wave packet carrying orbital angular momentum across scattering media
In this article, we experimentally generate a vortex space-time (ST) wave packet carrying orbital angular momentum (OAM) and confirm that the OAM of the beam survives after propagating either in the presence of a line obstruction or across a thin scattering medium.

| Summary: | In this article, we experimentally generate a vortex space-time (ST) wave packet carrying orbital angular momentum (OAM) and confirm that the OAM of the beam survives after propagating either in the presence of a line obstruction or across a thin scattering medium. A comparison of our findings with both Bessel and standard Gaussian beams carrying OAM reveals that ST-OAM wave packets exhibit a significantly higher mean Pearson’s correlation coefficient compared to these other beams. In addition, we employ a standard 3-mm thick glass microscope slide as a waveguide and find that the OAM belonging to ST wave packets remains protected after propagation. Our findings have potential utility in communication applications, sensing, imaging, and optical trapping. |
