Abstract
We present design of photonic integrated orbital angular momentum (OAM) emitters consisting of access waveguides and ring resonator with top grating made from holes. Access waveguides are coupled to the resonator using “pulleycoupler” scheme. The device is designed for silicon-on-insulator (SOI) manufacturing platform. We simulated singlemode resonator with one access waveguide and shown that it emits two OAM modes in out-of-plane regime. Than we simulated multimode resonator with two access waveguides and shown that it emits up to four OAM modes. The implementation of OAM emitter based on the ring resonator has specific resonance spectrum therefore such devices are WDM compatible. Compactness of such device allows using it in photonic integrated circuits.
