"wavelength-switched photonic neural network (WS-PNN) system... layering neural network... micro-ring resonators (MMR) used for neural network optical signal processing and provide reconfigurable switching... wavelength selective switches (WSS) inside broadcasting loop... WS-PNN support interconnection many neural networks through connecting multiple PNN chips with off-chip WSS... scalability  photonic neural networks support feedforward and recurrent neural network topologies"
