Image reconstruction in segmented waveguide arrays
Abstract
A simple design of spatially finite one-dimensional and bidimensional waveguide arrays, showing self-imaging properties, is proposed. Image reconstruction insensitive to array truncation is achieved by the introduction of short waveguide interruptions (waveguide segmentation), which act as a focusing lens for discretized light.

Introducing specific phase shifts by segmentation can yield image reconstruction for arbitrary 1D and 2D intensity distributions even in finite configurations with boundary reflections.
“Recently, it was suggested that introducing specific phase shifts to the propagating modes by a segmentation of the waveguide arrays can yield image reconstruction for arbitrary 1D and 2D intensity distributions even in finite configurations involving boundary reflections [60].”

Consequently, the light evolution in the second section will exactly reverse the one in the first and a full revival must occur in the initially excited channel.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
