Abstract
We propose and experimentally demonstrate an extended range of tunable optical delay obtained from four-wave mixing wavelength conversion and dispersion. The conversion bandwidth and the maximum delay are enlarged through dynamic control of the optical phase by gain-transparent stimulated Brillouin scattering. The delay range is increased by 37%. Bit-error-rate measurements show a maximum power penalty of 2.0 dB with reference to back-to-back performance. The technique can be applied to different configurations of tunable delay lines constructed with a fiber parametric process and dispersion.
