Abstract

We demonstrate an all-optical continuously tunable delay line based on wavelength conversion in semiconductor optical amplifier (SOA), and group-velocity dispersion (GVD) in dispersion-compensating fiber (DCF). The system operates, near 1550 nm, with a nonreturn-to-zero (NRZ) pattern at 10 Gb/s. The maximal delay up to 2700 ps is observed. The scheme achieves continuous control of a wide range of delays, wide signal bandwidth, nearly no pulse broadening and very little spectral distortion.
