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.

A silicon photonics chip is successfully employed for frequency multiplication of an 18.5-GHz clock up to 92.5GHz (×5) with low additional phase noise. The chip includes a 20-GHz phase modulator for comb generation and a thermally tunable distributed feedback resonator for reconfigurable spectral mode selection.

Connectivity in Multi-Band networks depends on the attainable optical performance for a number of system-level parameters like number of channels, modulation format and symbol rate. We present three connectivity schemes engaging E, S, C and L bands. Exploiting a rigorous OSNIR optimisation method we tabulate their optical reach and the corresponding performance trade-offs.

An overarching intelligent orchestrator is implemented to tailor, in real-time, the fixed-line end-to-end QoS-aware bandwidth slices to the wireless system, taking into account the status of the entire network.
