Opto-VLSI-based tuneable photonic RF filter

A tuneable photonic RF filter structure is proposed, and simulated. The structure comprises a reconfigurable Opto-VLSI processor, arrayed waveguide gratings, a fiber array, and high-dispersion fibres. The processor has the ability to generate positive and negative weights for realising arbitrary responses. The proof-of-concept of the tunable photonic RF signal processor is also experimentally demonstrated.
