Physical-layer security is often treated as a niche enhancement that is relevant only for ultra-sensitive links or exotic use cases. This view, however, may be dangerously outdated.

As optical infrastructures become more open, programmable, and widely shared, the attack...

As AI models reach unprecedented sizes, xPU cluster performance relies heavily on the scale-up network that tightly coordinates thousands of accelerators for distributed training workloads. Scaling up the xPU domain intensifies intra-domain communication demands, requiring higher...

For decades, intra-data center networks ("Scale-Out") and WDM data center interconnects ("Scale-Across") followed distinct technological evolutionary paths. Scale-Out DCNs relied on short-reach, O-band links using Intensity Modulation and Direct Detection (IMDD)....

Driven by explosive growth in cloud services and AI workloads, data center and transport networks have driven rapid advancements in optical technologies such as high-speed pluggable optics, coherent transmission, and open, software-driven architectures.

At the same time...

Hollow-core fibers (HCFs) promise ultra-low latency and negligible nonlinear penalties, potentially reshaping the design space of optical transmission. This workshop focuses on the system-level trade-offs enabled by HCFs and the end-to-end redesign choices they may trigger across...

Inside the data center, encompassing both intra- and inter-building campus links, optical interconnect technologies must deliver ever-increasing data rates under stringent constraints on cost, power, latency, and operational simplicity.

Intensity modulation direct...

Optical switching for AI has moved from research to hyperscale deployment; yet the field is fragmenting fast. MEMS, silicon photonics, and LCoS-based OCS compete across incompatible tradeoff spaces, while AI workloads are diverging: training tolerates millisecond reconfiguration...

This workshop is organized into two parts, focusing on capacity scaling in submarine and terrestrial/datacenter applications, respectively.

In submarine systems, scaling beyond today’s two-core architectures is increasingly limited by amplification under strict...

This workshop examines the balance between standardization and customization across next-generation optical interconnect architectures, including pluggable optics—such as eXtra-dense Pluggable Optics (XPO), co-packaged optics (CPO), and emerging near-package optics (NPO).

Driven by growing demand for optical interconnects in AI systems and data centers, integrated photonics is moving toward high-volume production. Yet the industry has no shared definition of a known good die: which measurements must be completed before committing to expensive...

As AI workloads scale globally, the physical layer faces unprecedented capacity, latency, and density demands. Although researchers keep pushing the performance limits of single-mode waveguides, operators prioritize protecting infrastructure investments and service stability. For...
