Abstract
We introduce an implementation of a Laplace differentiator based on a photonic crystal slab that operates at transmission mode. We show that the Laplace differentiator can be implemented provided that the guided resonances near the point exhibit an isotropic band structure. Such a device may facilitate nanophotonics-based optical analog computing for image processing.
