Networking & Interconnect
How chips and sites talk to each other. In scope: optical interconnect and co-packaged optics, scale-up vs scale-out fabrics, NVLink/InfiniBand/Ethernet economics, bandwidth per dollar, topology, cross-datacenter links. Out: memory bandwidth inside a package (hardware), photonic COMPUTE (out of the KB entirely).
Deep Neural Network Inference on an Integrated, Reconfigurable Photonic Tensor Processor
First production-ready photonic tensor processor for DNN inference — packaged in a 19-inch rack unit, PyTorch-integrated, MNIST + CIFAR-10 benchmarked. Runs pretrained networks without chip-specific retraining
Integrated Photonic Neural Network with On-Chip Backpropagation Training
First integrated photonic deep neural network with end-to-end on-chip gradient-descent backpropagation — all linear AND nonlinear computations on a single silicon photonic chip. 92.5% accuracy on 2D classification; automatically compensates for fabrication variations
