400-ns Continuously Tunable Delay of a 10-Gbps Intensity-Modulated Optical Signal
01 January 2009
A continuously tunable optical delay line based on a two-pump parametric process in highly nonlinear fiber provided a 400-ns tuning range for a 10-Gbps optical signal. This record 4005-bit delay used fixed dispersion elements, compatible with requirements for fast delay reconfiguration. The large delay range was facilitated by partial dispersion slope cancellation.
