Abstract

A stable $10\mathrm{GHz}$ pedestal-free short pulse generation scheme consisting of cascaded commercial ${\mathrm{LiNbO}}_3$ modulators has been proposed and successfully demonstrated experimentally. Fiber-based pulse compression and reshaping stages have been utilized to obtain a $1.38\mathrm{ps}$ optical pulse train with very little pedestal and $132\mathrm{fs}$ timing jitter. Excellent performance of multiplexing from $10\text{\hspace{0.17em} Gbits}/\mathrm{s}$ to $160\mathrm{Gbits}/\mathrm{s}$ using this method indicates good potential for application in ultrahigh-speed optical time-division-multiplexing systems.
