Invited Talk at Photonics West 2023
An invited talk on our scalable silicon photonic DWDM link architecture is given at SPIE Photonics West on February 3, 2023.

In this talk, we present a scalable architecture for multi-Tbps dense wavelength-division multiplexing (DWDM) silicon photonic transceivers leveraging Kerr frequency combs. The design introduces a multi-bus, even-odd channel interleaving scheme and a novel multi-FSR (free spectral range) arrangement, addressing the spectral and device limitations of traditional single-bus architectures. The design also accommodates various considerations, including fabrication robustness, thermal variations, and non-idealities in device and system performance. Full-link simulations validate the architecture’s efficacy, demonstrating error-free transmission across 64 channels, paving the way for next-generation, energy-efficient chip-to-chip connectivity in data centers and high-performance computing systems.
