Intensity-directed Equalizer for Chirp Compensation Enabling DML-based 56Gb/s PAM4 C-band Delivery over 35.9km SSMF

We propose an intensity-directed equalizer to address chirp induced eye skewing and intersymbol interference in DML-DD systems, and experimentally demonstrate a transmission of 56Gb/s PAM4 signals using a 16.8GHz C-band DML over 35.9 km SSMF.
