Abstract :
We demonstrate the integration of VCSEL array and vortex-beam-emitters, composed of double-ring-shaped Bragg-refiector waveguides functioning as diffraction element. A possibility of compact VCSEL-based emitters, creating and multiplexing vortex beams with different orbital momentums is suggested.
