Abstract
We show that a temporal effect equivalent to the spatial Talbot effect (self-imaging) applies to the reflection of periodic pulse trains from linearly chirped fiber gratings (LCFG’s). For specific input repetition periods the reflected signal is an exact replica of the input signal. Input repetition period values that give rise to this effect depend on the dispersion coefficient of the grating. We propose to use this effect as an alternative for dispersion measurement in LCFG’s. Furthermore, by using the properties of the temporal Talbot effect, we can design linear passive devices (LCFG’s) for use as frequency multipliers, able to multiply the repetition rate of a given pulse train.Keywords
