Experimental performance evaluation of analog signal transmission system with photonic integrated optical vortex emitter and 3.6 km few-mode fiber link

We experimentally demonstrate and evaluate the performance of analog signal transmission system with photonic integrated optical vortex emitter and 3.6 km few-mode fiber (FMF) link using OAM2 and OAM-2 modes and measured the spurious free dynamic range (SFDR) of the second-order harmonic distortion (SHD).
