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 8):
A method of producing an orbital angular momentum (\u201cOAM\u201d) laser emission, comprising:\n creating a first whisper-gallery mode (\u201cWGM\u201d) and a second WGM in a microring resonator using a pump beam, wherein the first WGM and second WGM are counter-propagating; causing the first WGM to become suppressed by creating an exceptional point; and outcoupling the second WGM as an OAM laser using modulations of an outer sidewall of the microring resonator.
