As a common feature of such devices one finds structures with dimensions in the order of the wavelength of the used light. To design and produce such devices, the wave nature of light must be taken into account. Accordingly, robust simulation tools are required which are based on rigorously solving Maxwell's equations, the governing equations of light propagation within macroscopic media. This thesis contributes to the modeling and the numerical computation of light scattering problems: Light scattering problems are typically posed on the entire space. The Perfectly-Matched -Layer method (PML) is widely used to restrict the simulation problem onto a bounded computational domain. We propose an adaptive PML method which exhibits a good convergence even for critical problems where standard PML implementations fail. Besides the computation of the near field, that is the electromagnetic field within the computational domain, it is of major interest to evaluate the electromagnetic field in the exterior domain and to compute the far field. So far, this was numerically only possible for simple geometries such as homogeneous exterior domains or layered media. To deal with more complicated devices, for example with waveguide inhomogeneities, we develop an evaluation formula based on the PML solution which allows for an exterior domain field evaluation in a half space above the device. Finally, we generalize the PML method to problems with multiply structured exterior domains. The term "multiply structured exterior domain" is defined in this thesis and means that the exterior domain exhibits several half-infinite structures. Mathematically, this gives rise to various complications. For example, no analytical solutions to Maxwell's equations for standard light sources are available in the exterior domain, which are needed to describe the incoming field in a light scattering problem. To tackle this we propose a new light scattering problem formulation which fits well into the PML method framework and which may be regarded as an extension of classical contributions by Sommerfeld, Wiener and Hopf. An exterior domain evaluation formula for multiply structured exterior domains with an extended illumination is derived as well.}, language = {en} } @incollection{SchmidtFrieseZschiedrichetal.2003, author = {Schmidt, Frank and Friese, T. and Zschiedrich, Lin and Deuflhard, Peter}, title = {Adaptive Multigrid Methods for the Vectorial Maxwell Eigenvalue Problem for Optical Waveguide Design}, series = {Mathematics - Key Technology for the Future}, booktitle = {Mathematics - Key Technology for the Future}, publisher = {Springer}, pages = {270 -- 292}, year = {2003}, language = {en} } @article{SchmidtHohageKloseetal.2008, author = {Schmidt, Frank and Hohage, Thorsten and Klose, Roland and Sch{\"a}dle, Achim and Zschiedrich, Lin}, title = {Pole condition: A numerical method for Helmholtz-type scattering problems with inhomogeneous exterior domain}, series = {J.

The finite element method (FEM) yields rigorous, high accuracy solutions of full 3D vectorial Maxwell's equations [1] and allows for great flexibility and accuracy in the geometrical modelling. Time-harmonic FEM solvers have been combined with Fourier methods in domain decomposition algorithms to compute coherent solutions of these coupled system. [2,3] The basic idea of a domain decomposition approach lies in a decomposition of the domain into smaller subdomains, separate calculations of the solutions and coupling of these solutions on adjacent subdomains. In experiments light sources are often not perfectly monochromatic and hence a comparision to simulation results might only be justified if the simulation results, which include interference patterns in the substrate, are spectrally averaged. In this contribution we present a scattering matrix domain decomposition algorithm for Maxwell's equations based on FEM. We study its convergence and advantages in the context of optical simulations of silicon thin film multi-junction solar cells. This allows for substrate light-trapping to be included in optical simulations and leads to a more realistic estimation of light path enhancement factors in thin-film devices near the band edge.}, language = {en} } @misc{AmiranashviliBandelowBlomeetal., author = {Amiranashvili, Shalva and Bandelow, Uwe and Blome, Mark and Burger, Sven and Schmidt, Frank and Schmidt, Kersten and Zschiedrich, Lin}, title = {Nanophotonics and nonlinear fiber optics}, series = {MATHEON-Mathematics for Key Technologies}, volume = {1}, journal = {MATHEON-Mathematics for Key Technologies}, editor = {Deuflhard, Peter and et al.,}, publisher = {European Mathematical Society}, doi = {10.4171/137}, pages = {257 -- 275}, language = {en} } @inproceedings{ZschiedrichBlomeGreiner, author = {Zschiedrich, Lin and Blome, Therese and Greiner, Horst}, title = {Simulation of advanced OLED light extraction structures with novel FEM methods}, series = {Organic Photonics VI}, volume = {9137}, booktitle = {Organic Photonics VI}, doi = {10.1117/12.2054146}, pages = {91370O}, language = {en} } @inproceedings{AbebeGomardZschiedrichetal., author = {Abebe, Muluneh G. and Gomard, Guillaume and Zschiedrich, Lin and Rockstuhl, Carsten and Paetzold, Ulrich W. and Abass, Aimi}, title = {Thermodynamics of Photon Recycling in Four Terminal Perovskite/si Tandem Solar Cells}, series = {Optical Nanostructures and Advanced Materials for Photovoltaics}, booktitle = {Optical Nanostructures and Advanced Materials for Photovoltaics}, doi = {10.1364/PV.2017.PM4A.2}, pages = {PM4A.2}, language = {en} } @article{SchneiderSrockaRodtetal., author = {Schneider, Philipp-Immanuel and Srocka, Nicole and Rodt, Sven and Zschiedrich, Lin and Reitzenstein, Stephan and Burger, Sven}, title = {Numerical optimization of the extraction efficiency of a quantum-dot based single-photon emitter into a single-mode fiber}, series = {Opt.

To construct geometrically accurate models of complex structured nano-photonic devices the finite element method (FEM) is ideally suited due to its flexibility in the geometrical modeling and superior convergence properties. Reduced order models such as the reduced basis method (RBM) allow to construct self-adaptive, error-controlled, very low dimensional approximations for input-output relationships which can be evaluated orders of magnitude faster than the full model. This is advantageous in applications requiring the solution of Maxwell's equations for multiple parameters or a single parameter but in real time. We present a reduced basis method for 3D Maxwell's equations based on the finite element method which allows variations of geometric as well as material and frequency parameters. We demonstrate accuracy and efficiency of the method for a light scattering problem exhibiting a resonance in the electric field.}, language = {en} } @inproceedings{HiremathZschiedrichBurgeretal., author = {Hiremath, Kirankumar and Zschiedrich, Lin and Burger, Sven and Schmidt, Frank}, title = {Finite elements based numerical solution of nonlocal hydrodynamic Drude model of nano-plasmonic scatterers}, series = {12th International Conference on Fiber Optics and Photonics}, booktitle = {12th International Conference on Fiber Optics and Photonics}, doi = {10.1364/PHOTONICS.2014.M3D.4}, pages = {M3D.4}, language = {en} } @article{ŻołnaczMusiałSrockaetal., author = {Żołnacz, Kinga and Musiał, Anna and Srocka, Nicole and Große, Jan and Schl{\"o}singer, Maximilian and Schneider, Philipp-Immanuel and Kravets, Oleh and Mikulicz, Monika and Olszewski, Jacek and Poturaj, Krzysztof and W{\´o}jcik, Grzegorz and Mergo, Paweł and Dybka, Kamil and Dyrkacz, Mariusz and Dłubek, Michał and Rodt, Sven and Burger, Sven and Zschiedrich, Lin and Sęk, Grzegorz and Reitzenstein, Stephan and Urbańczyk, Wacław}, title = {Method for direct coupling of a semiconductor quantum dot to an optical fiber for single-photon source applications}, series = {Opt.
