FIG. 1.

(a) Sketch of the 1D array configuration. (b) Microscope image of the segmented region. (c) Sketch of the 2D array configuration. (d) Microscope image of the front facet of the fabricated square lattice.

FIG. 2.

The light propagation in an unsegmented array is shown for (a) center and (b) surface waveguide excitations. When a segmentation is introduced, the diffraction is reversed so that the input plane is imaged on the output facet regardless of (c) center or (d) surface waveguide excitation. [(e) an (f)] the according simulations confirm the assumption of an abrupt phase shift, which is marked with a horizontal dashed line.

Image of FIG. 3.
FIG. 3.

The light distribution at the output facet of a 2D lattice without segmentation is shown in (a) and (b) for two different excitations. The corresponding simulations are shown in (c) and (d). The output distribution in the respective segmented arrays is shown in (e) and (f). The excited waveguides are marked with a white circle.
