【 摘 要 】

We experimentally demonstrate excitation of orbital angular momentum states in an air-core fiber by a silicon integrated vortex beam emitter which is designed and fabricated to match the modes supported by the fiber. The coupling loss is measured to be ~7.5 dB. Excitation of eigenmodes is confirmed by analyzing the fiber output.
