Photonic compressive sensing is a promising data compression method and has been successfully applied in high-speed RF signal detection with greatly reduced requirement for receiver bandwidth. A key challenge is due to the electronic bottleneck in high-speed random sequence generation and mixing. In this work, we propose and experimentally demonstrated for the first time all-optical random sequence...
High resolution microwave frequency measurement based on temporal channelization using a mode-locked laser is proposed and demonstrated. In the proposed system, a highly chirped optical pulse is modulated by a microwave signal with its frequency to be measured. The temporal microwave waveform is then mapped to the spectral domain thanks to dispersive Fourier transformation in a dispersive fiber. An...
Techniques to generate and process microwave and millimeter-wave arbitrary waveforms in the optical domain are reviewed, with an emphasis on the techniques implemented based on fiber optics.
