We propose and experimentally demonstrate a reconfigurable photonic RF differentiator based on a Kerr frequency comb generated in an integrated nonlinear microring resonator. The RF magnitude and phase responses are experimentally characterized. Systems demonstrations for Gaussian input signals are also performed.
A novel method to incorporate an optical Hilbert transformer with an all-optical photonic instantaneous frequency measurement system is proposed and demonstrated. Two orthogonal measurements of an RF signal are obtained which enables determination of both signal frequency and power. This system produces DC outputs that simplify the receiver and reduce cost. The system is demonstrated between DC and...
A novel instantaneous frequency measurement using all optical mixing is demonstrated. This system can provide RF frequency measurement while requiring no high speed electronic components and remoting all components of the measurement system to the receiver.
