Abstract This paper presents an ultra-energy-efficient MRM based 8-channel optical WDM NRZ transmitter, employing a scalable driver topology combined with monolithic electronic– photonic integration, which minimizes packaging parasitics and enables a compact design within a footprint of 0.018mm2 per-channel. The chip incorporates an autonomous concurrent wavelength-locking mechanism with near-zero static power consumption, achieving an aggregate data rate of 304Gb/s at 106fJ/b energy efficiency. High-performance computing systems and modern data centers are experiencing unprecedented compute demand driven by data-intensive applications such as generative artificial intelligence (AI). Optical links have emerged as a transformative interconnect solution within data centers, offering high bandwidth, low latency, and low loss. In particular, wavelength-division multiplexing (WDM) enables scaling in aggregate capacity by utilizing
