Temporal Talbot effect in free space
نویسندگان
چکیده
The temporal Talbot effect refers to the periodic revivals of a pulse train propagating in dispersive medium and is analog spatial with group-velocity dispersion time replacing diffraction space. Because typically large lengths, this has been observed date only single-mode fibers, rather than freely fields bulk media. Here we demonstrate for first time, best our knowledge, free space by employing space-time wave packets, whose spatiotemporal structure induces controllable magnitude sign

Fractional Talbot effect in phase space: A compact summation formula.
A phase space description of the fractional Talbot effect, occurring in a one--dimensional Fresnel diffraction from a periodic grating, is presented. Using the phase space formalism a compact summation formula for the Wigner function at rational multiples of the Talbot distance is derived. The summation formula shows that the fractional Talbot image in the phase space is generated by a finite s...
متن کاملNonlinear Talbot effect.
We propose and experimentally demonstrate the nonlinear Talbot effect from nonlinear photonic crystals. The nonlinear Talbot effect results from self-imaging of the generated periodic intensity pattern at the output surface of the crystal. To illustrate the effect, we experimentally observed second-harmonic Talbot self-imaging from 1D and 2D periodically poled LiTaO(3) crystals. Both integer an...
متن کاملTalbot effect in cylindrical waveguides
We extend the theory of Talbot revivals for planar or rectangular geometry to the case of cylindrical waveguides. We derive a list of conditions that are necessary to obtain revivals in cylindrical waveguides. A phase space approach based on the Wigner and the Kirkwood-Rihaczek functions provides a pictorial representation of TM modes interference associated with the Talbot effect.
متن کاملThe plasmon Talbot effect.
The plasmon analog of the self-imaging Talbot effect is described and theoretically analyzed. Rich plasmon carpets containing hot spots are shown to be produced by a row of periodically-spaced surface features. A row of holes drilled in a metal film and illuminated from the back side is discussed as a realizable implementation of this concept. Self-images of the row are produced, separated from...
متن کاملTemporal impulse response of the Talbot interferometer
The Talbot interferometer has been shown earlier to act as an optical tapped delay-line in the time domain. The interferometer is based on the self-imaging effect. It consists of two gratings separated by a multiple of the self-imaging distance. Here, we determine its temporal behaviour experimentally. First, the impulse response is measured directly in the time domain by means of femtosecond p...
