400-ns Continuously Tunable Delay of 10-Gb/s Intensity Modulated Optical Signal

A continuously tunable optical delay line based on a two-pump parametric process in a highly nonlinear fiber providing 400.5-ns range for a 10-Gb/s optical signal is reported. This record 4005-bit delay used fixed dispersion elements, compatible with requirements for fast delay reconfiguration. The large delay range was made possible by partial dispersion slope cancelation.
