Paper Abstract

An all-optical tunable delay line based on wavelength conversion in semiconductor optical amplifier (SOA), and group-velocity dispersion (GVD) in dispersion-compensating fiber (DCF) is theoretically analyzed and numerically demonstrated. By describing the basic theory, modeling and simulating the processes, we show that the scheme is feasible to produce large time delays. The system operates near 1550 nm, and with a nonreturn-to-zero (NRZ) pattern at 10 and 40 Gb/s, time delays from -3360 to 3360 ps are observed. The system achieves continuous control of a wide range of delays, wide signal bandwidth, nearly no pulse broadening, and very little spectral distortion.
