Tunable Pulse Delay Using Four-Wave Mixing in a 35-cm Bismuth Oxide Highly Nonlinear Fiber and Dispersion in a Chirped Fiber Bragg Grating

Optically-controlled variable delay of up to 185 ps is obtained for 10-GHz pulses using four-wave mixing and group velocity dispersion in a compact fiber-optic setup. The pulse shape remains unchanged over the delay range.
