| dc.description.abstract | A high-performance photonic sweeping-frequency (chirped) radio-frequency (RF) generator has been demonstrated. By use of a novel wavelength sweeping distributed-feedback (DFB) laser, which is operated based on the linewidth enhancement effect, a fixed wavelength narrow-linewidth DFB laser, and a wideband (dc to 50 GHz) photodiode module for the hetero-dyne beating RF signal generation, a very clear chirped RF waveform can be captured by a fast real-time scope. A very-high frequency sweeping rate (10.3 GHz/mu s) with an ultra-wide RF frequency sweeping range (similar to 40 GHz) have been demonstrated. The high-repeatability (similar to 97%) in sweeping frequency has been verified by analyzing tens of repetitive chirped waveforms. (C) 2013 Optical Society of America | en_US |
