Impact of Semiconductor Optical Amplifers On Performance & Power Consumption in Data Centers (UCSB)


A new technical paper titled “Integrated SOAs enable energy-efficient intra-data center coherent links” was published by researchers at UC Santa Barbara.

“In this work, we analyze the impact of integrated semiconductor optical amplifiers (SOAs) on link performance and power consumption, and describe the optimal design spaces for low-cost and energy-efficient coherent links. Placing SOAs after the modulator provide the most energy-efficient link budget improvement, up to 6 pJ/bit for large link budgets, despite any penalties from nonlinear impairments,” states the paper.
