Abstract:
The present disclosure describes a microring OAM laser producing an optical vortex beam with an on-demand topological charge and vector polarization states. This is enabled through combined index and gain/loss modulations at an EP, which breaks the mirror symmetry in the lasing generation dynamics and facilitates unidirectional power oscillation.

Claim (Index 1):
A device for emitting a laser beam having orbital angular momentum, the device comprising:\n a microring resonator made from a gain medium and having a top surface, a bottom surface opposite the top surface, and an outer sidewall, and wherein the outer sidewall is modulated for outcoupling the laser beam; and a refractive index grating disposed on the top surface of the microring resonator, the grating being configured such that the microring resonator has a refractive index which periodically alternates along the azimuth direction (\u03b8) to include a real component (n\u2032) and an imaginary component (n\u2033) to form an exceptional point where n\u2032=n\u2033.
