Abstract
Through theoretical analysis and experiment, we show that the performance of an ultrafast optical delay line using a time-prism pair is significantly improved when solition propagation is used between time-prisms. The enhancement is most dramatic for short pulses where dispersive pulse broadening in a linear propagation regime between time-prisms is large and limits perfomance. Experimentally, we demonstrate an optical delay line using soliton propagation in an all-fiber configuration allowing us to achieve a scan rate of 0.5 GHz, a delay range of 33.0 ps, no pre- and post-dispersion compensation, and a delay-to-pulse-width ratio of 6.0.
