Session Description:

The panel discussion will address technical status updates and ongoing developments related to Thin-Film Lithium Niobate (TFLN) photonics. Over the past years, TFLN has transitioned from a research-centered new material platform to becoming a strong candidate to provide practical solutions for next generation applications. In particular datacom, telecom and high-performance applications such as radio-over-fiber and measurement and test can benefit from TFLN attributes such as ultra-high electro-optic bandwidths, low driving voltages, compact size and cost effective production.

An Ecosystem Perspective on Scaling Integrated Photonics for the AI Revolution

Event Details

Session Description:

Artificial Intelligence and High-Performance Computing are accelerating the demand for next-generation optical interconnects, with photonic integrated circuits (PICs) as one of the key enablers of this (r)evolution. These wafer-based technologies are ideal for high channel count and high density optical interconnects such as In-Package Optical I/O and Co-Packaged Optics but have unique challenges. This panel will present the challenges and solutions of scaling PIC technology to the desired volumes as seen by different players across the ecosystem. It starts with the foundry, OSAT, and contract manufacturer to actually fabricate the photonic ICs. Wafer probing, and assembly/alignment equipment, in combination with scalable test & measurement solutions is next and play a critical role in the realization of these powerful interconnect technologies. And last but not least, the photonics developer and system integrator will also present their unique perspectives. One key aspect of this panel discussion is partner cooperation across the ecosystem, and how can companies in the industry effectively cooperate and standardize approaches to be able to cost-effectively scale PIC technology to high volumes.
