Patent Classification: ["372", "009000"]

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 10):
The method of  claim 9 , wherein the grating is configured such that the refractive index is n\u2032 2 \ue89e \u03c0 \ue89e \ue89e p / N < \u03b8 < 2 \ue89e \u03c0 \ue8a0 ( p + 1 4 ) / N \ue89e \ue89e and \ue89e \ue89e n \u2033 \ue89e \ue89e for \ue89e \ue89e 2 \ue89e \u03c0 ( p + 3 8 ) / N < \u03b8 < 2 \ue89e \u03c0 \ue8a0 ( p + 5 8 ) / N , \ue89e where N denotes the azimuthal number of a targeted whisper gallery mode and p takes integer values from the set {0, N\u22121}.
