Research
The optical spectroscopy group in the mid-infrared, specializes in the study of semiconductors and low-dimensional structures intended for use in emitters and detectors for the medium and long-wavelength infrared range. The research interests include quantum wells, heterojunctions, and quantum superlattices, as well as active regions of interband and quantum cascade lasers. The group also focuses on components of lasers with vertical cavity resonators, such as Bragg mirrors and subwavelength diffraction gratings.
In the area of basic characterization, studies are conducted using photoluminescence and photo absorption experiments employing an unconventional approach with a Fourier spectrometer use. For charge carrier dynamics measurements, experiments are carried out using a pump-probe setup with femtosecond time resolution.
By combining experimental methods, we aim to deepen the understanding of the physics behind advanced materials engineering. By discovering the structural and optical properties in various material systems, we contribute to improving the performance parameters of the final devices, ultimately for applications in various fields of life, such as defense, non-invasive medical diagnostics, and environmental protection.
