Enabling Equalization and Soft Decision by k-Means for VCSEL-Based PAM-4 Optical Interconnection

As for vertical-cavity surface-emitting lasers (VCSEL)-based optical pulse amplitude modulation (PAM) interconnection system, apart from the universal signal distortions like Gaussian noise and fiber dispersion, direct modulation of VCSEL specially induces level nonlinearity and level-dependent nois...
