This analysis expands our previous developments in the field. We analyze the effect of this new element on the behavior of light along the optical axis.4 p.application/pdfeng(c) Society of Photo-Optical Instrumentation Engineers (SPIE), 2019Fibres òptiquesMoment angular (Física nuclear)Optical fibersAngular momentum (Nuclear physics)On the behavior of vector light needles using modulation functions with topological chargeinfo:eu-repo/semantics/article6986022020-04-24info:eu-repo/semantics/openAccess
