Nonlinear Vector Autoregressor Equalization for PAM-4 Micro-Ring Modulator-based Short-Reach Transmission

We experimentally demonstrate a nonlinear vector autoregressor equalizer for 40 and 50 GBaud PAM-4 transmission with microring modulators and show that it outperforms both Volterra and reservoir computing-based equalizers in B2B and 2 km scenarios.
