Machine learning meets Singular Optics II: Single-pixel Detection of Structured Light
Purnesh Singh Badavath, Vijay Kumar
Structured light beams, including Laguerre-Gaussian (LG), Hermite-Gaussian (HG), and perfect vortex (PV) spatial modes, have been at the forefront of modern optics due to their pot…
Spatial-to-Temporal Orbital Angular Momentum Mapping in Twisted Light Fields
Vijay Kumar, Purnesh Singh Badavath
Optical angular momentum (OAM) in light beams is manifested as the two-dimensional spatial distribution of its complex amplitude, necessitating a 2D detector for its measurement. H…
