Paper Abstract

We proposed an all-optical tunable delay line based on wavelength conversion in semiconductor optical amplifiers (SOAs), and group-velocity dispersion (GVD) in single-mode fiber (SMF). The system operates in 1.5 μm window, with a nonreturn-to-zero (NRZ) pattern at 10 Gb/s. The maximal time delay up to 2600 ps is obtained. The scheme achieves continuous control of a wide range of delays, nearly no pulse broadening and very little spectral distortion.
