Will AIGC Requires Disruptive Optical Interconnect Technologies
As one of the key enabling technologies for industry 4.0, Artificial Intelligence (AI) has been a hot topic and attracted lots of attention in past decades in both academia and industries. With the recent emergence of ChatGPT, generative AI (AIGC) has made headlines everywhere. The generative AI, which allows for the creation of the original content by learning from existing data with machines, may revolutionize industries and transform the way companies operate in the near future.
With unprecedented amounts of computing power required, AIGC may reshape the IT infrastructure as well. It has been shown that the total amount of computing power for large model training has been doubling every three to four months, much faster than Moore’s law. Massive parallelism has to be used to provide such high computing power due to the speed limit of a single GPU chip, generating huge demands for optical interconnects, which has been manifested by recent demand surge for optical transceivers in the market.
Will AIGC requires significantly different optical interconnect technologies than current ones on form factors, bandwidth density, power consumption, latency et al? Can current optical interconnect technologies accommodate the AIGC demands? Will disruptive optical interconnect technologies be needed? This workshop will bring together experts from hyperscalers, AIGC service providers, optical interconnect product vendors and academia to discuss the challenges and opportunities that AIGC may bring to optical interconnects.

Reconfigurable Photonics Based on Phase Change Materials
Reconfigurable photonics provides a promising solution for manipulating the routing and phase delay within photonic systems, which is crucial for various applications including large-scale optical switching networks, neuromorphic computing, and active metasurfaces. However, traditional reconfigurable photonic components that rely on thermo-optic or electro-optic effects suffer from drawbacks such as high power consumption and large device footprint. These limitations prevent them from meeting the growing demand for scalability in photonic systems.
Phase change materials (PCM), such as chalcogenides and correlated oxides, exhibit a remarkable refractive index change during solid phase transitions. This unique property makes PCM an emerging and promising platform for reconfigurable photonics. By harnessing the extraordinary properties of PCM, it becomes possible to achieve efficient and compact reconfigurable photonic components. This advancement in reconfigurable photonics holds great potential for various applications and can pave the way for the future development of advanced optical technologies.

Advanced Algorithms for Future Optical Communication Systems
Since its emergence in 1970’s, optical fiber communication has deeply shaped the information society by providing the large-capacity infrastructure for data transportation. Especially in the last two decades, coherent communication and optical interconnect technologies based on digital signal processing has drastically increase the transmission data rate/capacity. The associated algorithms of the prevalent systems have become mature so far. However, to accommodate the continuous demand for low power consumption and large capacity for future optical communication systems, advanced algorithms are highly desired to tailor to different scenarios such as long-haul transmission, datacenter interconnect, 6G front haul, optical access networks, free-space optical communication, and so on.
This workshop will address the following questions on the emerging advance algorithms:
1) For optical interconnect, do we need direct detection with phase recovery or optical field reconstruction? How about the future development of low power consumption algorithm for coherent, IMDD and 6G front haul systems?
2) With artificial intelligence techniques entering optical communication field, how it enhances system ability of distortion monitoring and channel equalization? How about AI performance with constrained or limited resources? Could AI really speed up optical system modeling?
3) For future high-speed and high-capacity optical transmission, how much and what kind of benefit we can obtain from more sophisticated or intelligent algorithms? Shall we develop novel photonic simulation tools for emerging applications or building a new design paradigm?

Optical Switching and Interconnecting for Data Center Networks and High-Performance Computing
Current electrical switch technology in DCNs and HPC is expected to hit a wall in two generations from now due to the inability to increase the pin density on the Ball Grid Array (BGA) package. As a counterpart, switching the traffic in the optical domain has been investigated considerably as a solution to overcome the bandwidth bottleneck and latency issues. Benefiting from the optical transparency, the optical switching with high bandwidth is independent of the bit rate and data format of the traffic. WDM technology can be employed to boost the optical network capacity at a superior power-per-unit bandwidth performance. In addition, eliminating the power consuming optical-electrical-optical conversions at the switch nodes significantly improves the energy and cost-efficiency. However, the optical switches especially for the fast optical switches are not practically deployed in large-scale networks. What are the main challenges? And with the emergence of large-scale machine learning models, are there any opportunities for optical switching technologies?
This workshop will discuss the following questions on the optical switching technologies (suggestion):
1) For kinds of switches like SOA, AWGR + tunable laser, MEMS, and MZI, which solution is the most promising solution considering the reconfiguration time, switch radix, power loss, stability and cost, .ect?
2) Do we need fast optical packet switching? Whether the slow optical circuit switching can satisfy the requirements of DCN and HPC? like Google deployed the MEMS in Jupiter. What are the practical challenges to deploying optical switches in large-scale networks? Time Sync? CDR? Switch control? New topology?
3) Could artificial intelligence really enhance optical switching technologies? Can optical switching technology overcome bandwidth bottlenecks in large-scale machine learning models with >10,000 nodes? Apart from the switching capacity, are the cost and power consumption still advantages compared to electrical switches?
4) Different communities address these problems from a different perspective, how to compatible with the solutions from the optical, networking and computer sciences communities?
