Paper Abstract

We report an all-fibre interferometric autocorrelation measurement of femtosecond optical pulses in the C-band. An all-fibre Mach-Zehnder interferometer with piezo-electric fiber stretcher in one arm provides the interference signal. A highly nonlinear and dispersion shifted fibre with Kerr coefficient 10.5 /W-km generates an idler by the process of degenerate four wave mixing of the pump and target pulse signals. The idler intensity is proportional to the interferometric autocorrelation of target pulse. We have measured approximately 100 fs optical pulses at 1552.52nm from an actively mode locked erbium doped fibre laser operating at 280 MHz repetition rate.
