Presentation | How are micro-optics driving next-generation optical communications

Thursday 12 September, Dr. Wilfried Noell, Chief Scientist at Focuslight, delivering an online presentation at The 25th China International Optoelectronic Exposition (CIOE 2024) on the topic of “How are micro-optics driving next-generation optical communications?”

Summary

Next-generation optical interconnects in data center’s and artificial intelligence (AI) / large language model (LLM) clusters are facing a number of challenges due to factors such as increased bandwidth demand, the need for ultra-low latency, and high power consumption. The significant growth in data traffic from AI applications requires scalable and energy-efficient solutions, and integrating advanced optical technology with existing infrastructure can be complex. Ensuring reliability and durability under rigorous demands is essential, and balancing performance improvements with cost-effectiveness remains a critical hurdle for widespread adoption.

The presentation has examined refractive and diffractive micro-optics as a solution, looking at how they can drive frontier applications in next-generation optical communications. It has also detailed how refractive and diffractive micro/nano-optics can enable PICs and optical switches.
