  Supersymmetric (SUSY) optical structures provide a versatile platform to
manipulate the scattering and localization properties of light, with potential
applications to mode conversion, spatial multiplexing and invisible devices.
Here we show that SUSY can be exploited to realize broadband transparent
intersections between guiding structures in optical networks for both
continuous and discretized light. These include transparent crossing of
high-contrast-index waveguides and directional couplers, as well as crossing of
guiding channels in coupled resonator lattices.
