We propose a multiplier-less deep neural network (DNN) to mitigate fiber-nonlinear distortion of shaped constellations. Our DNN achieves an excellent performance-complexity trade-off with progressive lottery ticket hypothesis (LHT) weight pruning and additive powers-of-two (APoT) quantization.

A flexible optical switch and control system with dynamic bandwidth allocation is experimentally assessed to enable reconfigurable DCNs. Experiments validate the flexible system achieves 3.15 µs end-to-end latency (improving 48.61%) and decreases one order magnitude of packet loss, compared with the scheme with fixed connections.

We simulated tensor-train decomposed neural networks realized by Mach-Zehnder interferometer-based scalable photonic neuromorphic devices. The simulation results demonstrate that under practical hardware imprecisions, the TT-decomposed neural networks can achieve >90% test accuracy with 33.6× fewer MZIs than conventional photonic neural network implementations.
