Vortex 4.0 on chip

摘要

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