    "abstract": "We present a finite-element simulation tool for calculating light fields in\n3D nano-optical devices. This allows to solve challenging problems on a\nstandard personal computer. We present solutions to eigenvalue problems, like\nBloch-type eigenvalues in photonic crystals and photonic crystal waveguides,\nand to scattering problems, like the transmission through finite photonic\ncrystals.\n  The discretization is based on unstructured tetrahedral grids with an\nadaptive grid refinement controlled and steered by an error-estimator. As\nansatz functions we use higher order, vectorial elements (Nedelec, edge\nelements). For a fast convergence of the solution we make use of advanced\nmulti-grid algorithms adapted for the vectorial Maxwell\u0027s equations.",
