Nonlinear characteristics of RF photonic processing system

Photonic technology can be applied for processing wideband signals in RF system, which can overcome some difficulty in traditional RF and digital signal processing systems. RF signal power can determine the ability of RF photonic system. When input RF signal power arrives to a great extent, the photonic system can provide some new frequency terms because of nonlinear effects. In this paper, nonlinear characteristics of RF photonic processing system are investigated, and results in theory and experiment are demonstrated.
