WebJan 1, 2013 · The coupling characteristics of the finite waveguide arrays are analyzed by taking into account the coupling between the non-adjacent waveguides. The sufficient condition to achieve Talbot effect in the waveguide arrays is discussed. The results show that the condition is more rigorous than that obtained by only considering adjacent coupling. WebUnlike continuous systems where the Talbot self-imaging effect always occurs irrespective of the pattern period, in discrete configurations this process is only possible for a …

Webdiscrete Talbot effects in weakly coupled waveguide ar-rays. Our theoretical analysis indicates that Talbot recur-rences occur only when the period Nof the initial pattern belongs to the set N2f1;2;3;4;6g. This is unlike what occurs in the continuous Talbot process where the revivals are period independent. Our experimental results were
WebMay 19, 2008 · Discrete Talbot effect is only possible for just a few pattern periodicities which belong to the set N ∈ { 2, 3, 4, 6 } [17], while for any other pattern period its propagation becomes aperiodic [see an example for N = 7 in Fig. 3 (a)]. Also, the pattern must be necessarily periodic and infinite [or very wide in practical conditions]. sharing hilton honors pointsWebThe diffraction pattern is reproduced completely at detection positions of an integer multiple of twice the Talbot lengths. Meanwhile, the fractional Talbot effect, presented as complicated subimages at special positions, is also clearly observed.
