High repetition rate frequency combs and pulse trains are generated from continuous-wave lasers either by strong electro-optic modulation or by nonlinear wave mixing in microresonators. Applications to optical and RF arbitrary waveform generation and signal processing are discussed.
In summary we demonstrate the application of programmable microwave photonic phase filters to compensate a broadband antenna dispersion at a receiver front which enables to increase data rate by overcoming distortion due to antenna nonlinear spectral phase. We also show that dispersion-compensation combined with matched filtering arbitrary waveforms can be used in waveform detection. Our scheme is...
We demonstrate ultra-compact spectral shaping via thermo-optically tunable multiple-channel microring resonators on a silicon chip, and combine it with frequency-time mapping to achieve photonic radio-frequency arbitrary waveform generation (RFAWG).
We demonstrate broadband antenna dispersion compensation and matched-filtering using microwave photonic filters implemented by optical pulse shaping. We compensate undesirable dispersion to overcome distortion introduced by nonlinear spectral phase and perform matched-filtering for waveform identification.

We demonstrate matched filtering of ultrawideband radio frequency waveforms via programmable optical phase filters implemented in a hyperfine resolution pulse shaper. As an example we demonstrate compression of frequency modulated and pseudorandom sequence waveforms.

In this work, we experimentally demonstrate the capability to compensate for dispersion effects in several types of broadband antenna through photonic-synthesis of tailored electronic excitation waveforms.
