Following the demand for 1.6 Tbps and beyond data rates and lower power consumption transceivers in data center networks and related systems, we present the first 16-channel directly modulated laser (DML) array exhibiting the photon-photon resonance (PPR) effect. Bandwidths of &#x223C;50 GHz at bias currents between 6.1 &#x223C; 9.2 mA were achieved for all 16 channels in a membrane laser array on SiO 2 &#x002F;Si with optimized integrated optical feedback for stable PPR control, denoting a record bandwidth &#x00D7; no. channel product. The DML array has been demonstrated in an O-band short-reach link by using 100-GBaud NRZ modulations, resulting in &lt;130 fJ&#x002F;bit laser-operating energies. These results denote a significant stride towards ultra-low power consumption DML transmitters for 1.6 Tbps interconnects and beyond.
