    (Color online) (a) Effect of dispersion compensation on broadening the frequency tunable range of the OEO. (b) Effect of the combination of an EDFA and FBG on the SNR of the frequency-beaten signal. (c) Spectra of the generated microwave signal at different frequencies. The frequency is tuned from 3 to 45 GHz. (d) SSB phase noise of the oscillation frequencies at 4.81, 24.41, and 44.30 GHz, which are generated by the DCOEO.
    (a) Generated temporal waveform and (b) the recovered instantaneous frequency profile of the linearly frequency-chirped 27 GHz signal with 10 MHz bandwidth, and (c) the waveform and (d) the recovered phase profile of the 10 Mb/s phase-coded 27 GHz signal.
    (a) Generated temporal waveform and (b) the recovered instantaneous frequency profile of the linearly frequency-chirped 27 GHz signal with 10 GHz bandwidth, and (c) the waveform and (d) the recovered phase profile of the 10 Gb/s phase-coded 27 GHz signal.
    Calculated autocorrelation of the phase-coded microwave waveforms with a carrier frequency of 27 GHz, and a Baker phase-coding signal with a length of 13 bit at (a) 10 Mb/s and (b) 10 Gb/s.
    (a) Generated temporal waveform and (b) the recovered instantaneous frequency profile of the linearly frequency-chirped 4 GHz signal with 2 GHz bandwidth, and (c) the waveform and (d) the recovered phase profile of the 2 Gb/s phase-coded 27 GHz signal.
