Abstract
We present our work in optical generation of arbitrarily shaped
millimeter-wave electromagnetic waveforms. Through a novel technique,
which utilizes tailored optical pulse sequences from a direct
space-to-time pulse shaper to drive a high-speed optical-to-electrical
converter, we generate amplitude-equalized, arbitrarily phase-and
frequency-modulated waveforms at center frequencies approaching 50 GHz. In
addition, we demonstrate the extension of this technique to generation of
arbitrary electromagnetic waveforms in the low-gigahertz range, through
dispersive stretching of the pulse shaper output. In the dispersively
stretched configuration, the duration of our electrical waveforms is tuned
through simple alignment changes in our pulse-shaping
apparatus.
