Various topics for Master's theses (30 credits, 6 months) are available in the in the field of computational meta-photonics and integrated optics. Prof. Calà Lesina is a member of PhoenixD and team leader of the research group "Computational Photonics" at HOT - Hannover Centre for Optical Technologies.
The following topics are available:
1) Inverse design of metasurfaces integrated on the tip of optical fibers
Optical metasurfaces represent a revolutionary platform to manipulate the behaviour of light at the nanoscale. They can reduce the footprint of traditional optical components, and achieve optical properties otherwise not available (beam steering, wavefront manipulation, polarization control, etc), thus finding applications in all domains of optics and photonics. The student will work with the simulation software Ansys Lumerical, Meep, and/or Tidy3D, also exploiting high-performance computing, to perform the inverse design via topology optimization of metasurfaces realized on the tip of optical fibers.
2) Inverse design of integrated optics for single photon emission and routing
Complex integrated optical waveguides can be designed to promote the emission of single photons from quantum dots and direct the radiation along a desired path. This finds applications in optical computing and quantum technologies. The student will work with the simulation software Ansys Lumerical, Meep, and/or Tidy3D, also exploiting high-performance computing, to perform the inverse design via topology optimization of integrated optical waveguides to enhance photon emission and propagation in a desired direction through the optical circuit.
Required qualifications for all theses:
- Excellent communication in English
- Knowledge of at least one programming language (python, Matlab, C++)
- Knowledge of wave optics and electromagnetics
To apply please send CV and transcripts to the office of Prof. Antonio Calà Lesina (office-calalesina@hot.uni-hannover.de).
Depending on the candidate's qualifications, these topics can also be adapted to fit the amount of work and duration of a project (10 credits, 3 months).
