We experimentally and numerically investigate the minimum electrical bandwidth for 50GBaud PAM4 detection with polybinary spectral shaping. With only 19GHz electrical brick-wall bandwidth, 100Gb/s PAM-4 transmission is demonstrated with 24% bandwidth compression at BTB and 1km SSMF scenarios.

We experimentally demonstrate a 100-Gbit/s 16-QAM free-space optical link using/tailoring an optical bottle beam to circumvent obstructions with different sizes and locations. Experimental results show ~10-dB less obstruction-induced power penalty compared to using a Gaussian beam for the obstruction with a diameter of ~4.5 mm.

An original microring-based filter exploiting non-rational Vernier scheme and controllable ring losses with FSR-free frequency response and wide range hitless tuneability is reported. Effectiveness of the device as Add/Drop multiplexer is demonstrated through BER assessments on 200 Gbit/s 16-QAM DP signals.

We present a channel response-aware Photonic Neural Network (PNN) and demonstrate experimentally its resilience in Inter-Symbol Interference (ISI) when implemented in an integrated neuron. The trained PNN model performs at 25GMAC/sec/axon using only 7GHz-bandwidth photonic axons with 97.37% accuracy in the MNIST dataset.
