- Development of the optical system for volumetric 3D printing.

• Transient reflectivity pump-probe spectroscopy measurements with ultrashort laser pulses • ‘Improving the signal-to-noise ratio in pump-probe measurements’ by increasing the modulation frequency with an optomechanical MEMS modulator. Re-built the setup and tested (M.Sc. thesis) • Tests of an adaptive optics component use in a dispersion-scan system for laser pulses characterization Supervisor: Prof. Dr. Günter Steinmeyer

• Development and support of the Industry 4.0 project for remote communication and troubleshooting • Technical development of the components setup • Independent communication and coordination of the pilot phase with production • Execution of the project documentation; development of a feedback and evaluation catalog for the pilot phase • Feasibility study of the wireless extension of photo-documentation application • Case study on the use of AR-glasses in manufacturing

Light Technology Institute (LTI) Perovskite Solar Cells, cleanroom laboratory: • Thin films processing varying a tin-oxide layer • Electrical properties characterization on a solar simulator

Built 2 optical measurement systems and wrote software (LabVIEW) for signal data processing: • SPIDER system (Spectral Phase Interferometry for Direct Electric-field Reconstruction) for characterization of ultrashort laser pulses centered at 1030 nm (B.Sc.Eng. thesis) – 2nd prize in national competition for best thesis in optoelectronics • Fourier Spectrometer • Optical fibers splicing and fabrication of tapered fibers for mode filtering in fiber lasers

Institute of Micromechanics and Photonics Numerical simulations in MATLAB for optical interferometric Bessel fringe patterns: • Phase retrieval using Temporal Phase Shifting algorithms • Noise filtering procedures with optimization using Partial Differential Equations (in a project regarding optoelectronic measurement systems used for vibrations characterization)
