Although the benefits of FPGAs for accelerating scientific codes are widely acknowledged, the use of FPGA accelerators in scientific computing is not widespread because reaping these benefits requires knowledge of hardware design methods and tools that is typically not available with domain scientists. A promising but hardly investigated approach is to(More)
Finite difference methods are widely used, highly parallel algorithms for solving differential equations. However, the algorithms are memory bound and thus difficult to implement efficiently on CPUs or GPUs. In this work we study the implementation of the finite difference time domain (FDTD) method for solving Maxwell's equations on an FPGA-based Maxeler(More)
resistance to increase until that area is depleted causing the voids to coalesce which causes the local temperature and current density to drop and consequently the resistance drops. A critical film temperature T c = 254 C was identified at which the maximum height M of resistance transient reaches a peak value M p as a function of current density. In(More)
The coherent state preparation and control of single quantum systems is an important prerequisite for the implementation of functional quantum devices. Prominent examples for such systems are semiconductor quantum dots, which exhibit a fine structure split single exciton state and a V-type three level structure, given by a common ground state and two(More)
Oblique semi-guided light propagation across linear folds of slab waveguides is being considered. Exploiting a Fabry-Perot-like resonance effect, we observe virtually full transmission of laterally plane waves, and of laterally wide semi-guided beams, through step configurations consisting of two sharp 90 • waveguide corners. Incidence of semi-guided waves(More)
Sheets of slab waveguides with sharp corners are investigated. By means of rigorous numerical experiments, we look at oblique incidence of semi-guided plane waves. Radiation losses vanish beyond a certain critical angle of incidence. One can thus realize lossless propagation through 90-degree corner configurations, where the remaining guided waves are still(More)
