We experimentally demonstrate a novel all-optical all-fiberized pulse retiming scheme incorporating parabolic pulses generated in a linear fashion through pulse shaping in a superstructured fiber Bragg grating. The scheme relies on chirping the signal to be retimed using cross-phase modulation with the broader parabolic clock pulses, and subsequently retiming it through linear propagation in a dispersive medium. We demonstrate the cancellation of up to 4-ps root-mean-square timing jitter for$sim$2-ps data.

OFDM has emerged as a promising modulation technique in long-haul and access optical networks. The computational complexity of the format can be met with powerful digital signal processors； and especially by exploiting all-optical signal processing.

An optical sampling oscilloscope is used to characterize short pulses which have been shaped using superstructured FBGs. The performance of square-pulse-generating and pulse-multiplying gratings are examined directly in real time, with a resolution of 2ps, excellent pulse quality is confirmed.
