Abstract

The optical pulse trains at a multiplied repetition frequency is generated by Fractional Talbot effects in optical fiber. The principles of Talbot effects and Fractional Talbot effects in fiber are analyzed in this paper. The 20GHz, 40GHz and 50GHz optical pulse trains are obtained from the original pulse trains with 2.8ps width at 10GHz repetition frequency. An optical pulse at 40GHz repetition frequency is also produced by upshifting the repetition frequency of 5GHz pulse trains. The degradation of 40GHz and 50GHz pulse trains is discussed by spectrum analysis of the pulse trains and some methods are proposed to enhance the performance of the pulse trains.
