Abstract
Broadband Fiber OAM (De)multiplexer
A fiber-based broadband orbital angular momentum (OAM)-(de)multiplexer is presented which is realized with a dielectric waveguide structure. The structure design is based on the adiabatic principle, as utilized in photonic lanterns for highly efficient conversion of spatially separated single modes into eigenmodes. An artificial magnetic field is introduced by twisting the structure to lift the degeneracy of the OAM modes. By combining these two principles, the structure is able to effectively (de)multiplex multiple OAM beams at different wavelengths simultaneously from/into spatially separable single-mode waveguides. For further details, see article number 2302597 by Julian Schulz and Georg von Freymann.
