| Research topics: Things we have been / are busy with, including a bunch of figures. Keywords: Theoretical photonics, integrated optics, numerical modeling; dielectric waveguide theory, mode solvers; interferometric devices, nonreciprocal integrated optical devices; polarizer / isolator / circulator concepts; microresonator simulations ... |
| Publications: References to journal papers, book chapters, and contributions to conference proceedings, a list of talks and poster presentations, and links to postscript versions of my PhD- and Diploma theses. |
| Teaching: Information about the courses and MSc projects (finished and upcoming) where I am involved in. |
| Metric: Tools for semianalytic modeling in integrated optics / photonics, simulations of lossless 2D configurations with rectangular refractive index distributions. Includes a mode solver engine for dielectric multilayer slab waveguides, and solvers for guided-wave Helmholtz (-scattering) problems based on spectral discretizations along one (BEP: bidirectional eigenmode propagation) or two coordinate axes (QUEP: quadridirectional eigenmode propagation). A series of application examples, embedded in the html manual, complements the downloadable, commented C++ sources. |
| WMM: A quasianalytic mode solver for rectangular dielectric integrated optical waveguide channels (3D configurations with 2D cross sections), programmed during my PhD period at the Department of Physics, University of Osnabrück, Germany. The html manual includes the downloadable, commented C++ sources, accompanied by several application examples. |
| OMS: A mode solver for optical dielectric multilayer slab waveguides with 1D cross sections. Following the waveguide definition in terms of refractive indices, layer thicknesses, and the vacuum wavelength, the Java applet calculates the propagation constants / effective indices of guided modes and allows to inspect the corresponding optical field patterns. It is intended as a basic tool for integrated optics design, in particular for purposes of demonstration. |
| EIMS: Similar to its 1D counterpart, this applet calculates and visualizes the guided fields of dielectric integrated optical waveguides with two-dimensional light confinement and weak lateral guiding. Note the remarks on the effective-index approximation the mode solver relies on. |
| Teval: A Java applet that can evaluate simple C-style expressions. The applet knows about the numerical values of some common physical constants, hence it is in particular useful for a certain class of basic exercises in physics courses ... |
| Bookmarks: Links that I find nice or useful or that I found once nice or useful. |
