Time-transformation technique for generation of optical pulse multiplets in a single mode anomalous dispersion optical fiber.

We present the generation of optical pulse multiplets in the temporal domain from a single pulse using the time-transformation technique for the first time, to the best of our knowledge. The generation of a pair of compressed, well-spaced, and identical Gaussian pulses from a third-order super-Gaussian input pulse when propagated through an anomalous dispersion fiber is reported. Detailed analysis on the effect of variation of input energy, pulse parameters, and optical gain in view of doublet formation leading to the possibility of high effective repetition rate (ERR) at smaller propagating length is reported. The formation of triplets and quadruplets from different input pulse shapes is investigated.
