Abstract: Given the expanding landscape of data-intensive applications, such as cloud computing, metaverse, and generative artificial intelligence, the demand for higher-speed data transmission and computation continues to escalate. Silicon (Si) photonics has emerged as a promising technology for next- generation optical interconnects and accelerators because of its ultra-high speed, low-latency, CMOS compatibility, and economies of scale. In this talk, learn about a Si-first photonic integrated platform, where modulators, photodetectors, linear multipliers, and optical memories can all be implemented exclusively using Si. This pure-Si scheme minimizes the efforts for regrowth or wafer bonding of additional materials, offering substantial advantages in terms of reducing threshold, time, cost, and simultaneously enhancing fabrication yield and reliability for Si photonics foundries. It paves the way for large-scale integrated photonic circuits, providing easily accessible hardware with ultra-fast speeds and enhanced features for a wide range of optical systems, including interconnects, neural networks and sensing.
