1.56-mu s continuously tunable parametric delay line for a 40-Gb/s signal
06 July 2009
Experimental demonstration of an all-fiber, all-optical continuously tunable delay line is reported. The 1.56-mu s delay with a record 62,400 time-delay bit-rate product was characterized for a 40-Gbps data channel. The result was enabled by parametric dispersion compensation with cascaded triple-conversion in highly-nonlinear fiber capable of continuous tuning over 39.5 nm. (C) 2009 Optical Society of America
