Integrated Systems and Photonics

Bachelor’s lab course in simulation of optical sensors


This internship is conducted in German language.

Information about the lab course:

In the simulation of optical sensors you will learn how to simulate sensors using the Finite Element Method (FEM). This simulation method is widely used in industry and research. It allows the approximate calculation of the mechanical, electrical, magnetic, optical and thermal behavior of arbitrarily shaped assemblies. The properties can be analyzed individually as well as coupled and additional physical properties can be added. During the internship the software COMSOL Multiphysics® is used. The focus of the internship is the practical application of the finite element method using the example of optical sensors such as ring, plasmon and waveguide resonators. The mathematical foundations of the methodology can be learned before or afterwards in other modules. The internship is divided into three phases. In addition to skills in computer simulation, you will learn in particular knowledge and skills in scientific work. Part of the internship is designed as a project phase in which you simulatively explore the behavior of a self-selected sensor structure.


Phase 1: Learning simulation and research methods (5 weeks)


  • Optical sensors
  • Simulations with the finite element method (FEM)
  • Data analysis (e.g., with Matlab)
  • The research cycle


Phase 2: Developing a computer simulation on your own research question (5 weeks)


  • Project work in pairs
  • Weekly interim discussions


Phase 3: Evaluation, interpretation, presentation of the results (2 weeks)


Recommended prerequisites: Mathematics for engineering I-III or equivalent as well as programming knowledge.

The course is also suitable for students from other disciplines, who would like to try out scientific computing on a practical research question.
