The AI industry is facing a critical bottleneck in data center interconnects, as traditional copper cabling has reached its physical and supply limits. Photonics, or optical interconnects, are emerging as the leading solution to enable higher bandwidth and lower latency communication between the increasing number of accelerators required for AI computations. Companies like Lightmatter are developing advanced optical solutions, such as co-packaged optics (CPO) and on-interposer optics, with significant industry adoption expected around 2027-2028, aiming to overcome the limitations of Moore's Law and facilitate the next paradigm of computing scale. AI
