To meet the flexible and integrated requirements of future optical networks, we propose the optical filter with variable waveform shape using on-chip photonic reservoir computing neural network. The on-chip photonic reservoir computing neural network implements a hardware network directly to mitigate the latency and power-consumption. Combined with linear regression algorithm, infinite (IIR) and finite (FIR) impulse response optical filters are realized. Compared with the traditional filters, this filter obtains more flexible and higher integration. In future, this filter can be widely used in integrated microwave photonics and wavelength division multiplexing systems.
