Regular biography
Aleksandar D. Rakić is a leading researcher in the field of terahertz (THz) and mid-infrared (MIR) photonics, with a particular focus on quantum cascade lasers (QCLs) and their applications in sensing, imaging, and spectroscopy. His work explores the interaction between light and matter at terahertz frequencies, leveraging the unique properties of QCLs for high-resolution, non-invasive measurements. Rakić has made significant contributions to the development of laser feedback interferometry (LFI) and self-mixing techniques, which enable real-time, high-sensitivity detection of biological and material properties. His research spans a wide range of applications, including hydration sensing in plants, skin pathology imaging, and the characterization of nanoscale materials. Rakić is also known for his work on frequency combs in QCLs, which have implications for precision spectroscopy and optical communications. His interdisciplinary approach combines physics, engineering, and biology, and he has published extensively in top-tier journals such as *Optics Express*, *Biomedical Optics Express*, *APL Photonics*, and *Sensors*. He has also contributed to the development of novel optical systems for biomedical and environmental monitoring, demonstrating the practical impact of his research. Rakić's work is characterized by its innovation, technical depth, and real-world relevance, making him a prominent figure in the field of THz and MIR photonics.
