We demonstrate the use of integrated micro-resonator based optical frequency comb sources as the basis for transversal filtering functions for microwave and radio frequency photonic filtering and advanced functions.
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.
An experimentally demonstrated temporal Hilbert transformer based on an integrated optical frequency comb source is exploited to obtain the temporal Hilbert transform of a Gaussian pulse with a full-width half maximum duration of 0.12ns.
A novel technique for correlation of spectrally encoded data is presented. Data encoded in the spectrum of ultrafast optical pulses is mapped into the time domain using dispersion and then mixed with a spectrally engineered broadband pump using four wave mixing to create a narrow bandwidth idler, which is isolated and electronically integrated. Unlike previous methods, this solution provides all-optical...
