Active multi‐core fibers represent a powerful platform for coding information via power, phase, frequency, and topological charge, as presented by Petra P. Beličev, Sergei Turitsyn, and co‐workers in article number 2100108. Depending on the gain distribution between the periphery and central core, the system supports multiple functions in applications: from high‐power fiber lasers to vortex carriers and selective topological charge switchers.
