Abstract :
We demonstrate optical true time delays using wavelength conversion coupled with chromatic dispersion. Using offset pumps, <; 1 dB magnitude response fluctuations over ~40 GHz of bandwidth is achieved. Calculated linear frequency-modulated impulse response maintains a <;-32 dB peak-to-sidelobe-ratio.
