Abstract
We experimentally demonstrate and evaluate the performance of an analog signal transmission systemwith photonic integrated optical vortex emitter and 3.6-km few-mode fiber (FMF) link using orbital angular momentum (OAM) modes. The fabricated photonic integrated device is capable of emitting vector optical vortices carrying well-defined and quantized OAM modes with topological charge l = -2 and 2. After propagating through 3.6-km FMF, we measure and assess the spurious free dynamic range of the second-order harmonic distortion. Moreover, we study the impact of nonlinearity- induced resonance wavelength shift of the optical vortex emitter on the analog link performance as increasing the input optical power.
