Abstract :
Summary form only given. We demonstrate a broadband (140 nm) supercontinuum (SC) source that has broad flat region (40 nm), high-power spectral density (7.9 dBm/nm), high coherence and potentially high temporal resolution. Compared with other sources used in analog-to-digital (A/D) conversion, short fiber SC simultaneously has quadrupled uniform spectral width, nearly doubled bandwidth and eight times better temporal resolution (/spl sim/5 ps). Based on the parameters of our SC source, we estimate that sampling of continuous signals with <10% pulse-to-pulse variation and up to 400 GSa/s with 1-nm filter spacing is achievable.
