Abstract
Radio frequency (RF) signal processors based on photonics have several advantages, such as broadband capability, immunity to electromagnetic interference, flexibility, and light weight in comparison to all-electronics RF filters. It still requires innovative research and development to achieve high-resolution reconfigurable photonic RF signal processors featuring high selectivity, resolution, wide tunability, and fast reconfigurability. In this paper, we propose and experimentally demonstrate the concept of a reconfigurable photonic RF filter structure integrating an Amplified Spontaneous Emission (ASE) source, an Opto-VLSI processor that generates arbitrary phase-only steering and multicasting holograms for wavelength selection and attenuation, arrayed waveguide gratings (AWGs) for waveband multiplexing and demultiplexing, high-dispersion fibres for RF delay synthesis, and a balanced photodetector for generating positive and negative processor weights. Independent control of the weights of a reconfigurable photonic RF filter is experimentally demonstrated.
