The orbital angular momentum (OAM) of light has promising applications, ranging from information multiplexing andhigh-speed optical communication to computation. Dynamically tunable and switchable vortex microlasers combinedwith direct photocurrent detection of the topological charges of OAM states have paved unexplored routes for thedevelopment and integration of fourth-generation (4.0) vortex technology, potentially on chip.
