Professor Wasilewski’s research interests include Molecular Beam Epitaxy (MBE) and nanofabrication of III-V semiconductor structures for quantum optics, nano-photonics, nano-electronics and quantum computing applications. The MBE laboratory, led by Professor Wasilewski, has demonstrated the world’s highest operating temperatures for GaAs/AlGaAs-based THz Quantum Cascade Lasers. These devices are among the most complex man-made quantum structures. In addition, the MBE laboratory also originally developed the In-flush method, which is the best technique for creating and fine-tuning MBE-grown InAs/GaAs quantum dots (QDs) systems. Professor Wasilewski is a co-author of close to 500 refereed journal articles and conference proceedings with some of the highest citation records in the field (close to 15,000 citations to his work with an h-index of 61). In 2012, Professor Wasilewski was awarded the title of Professor of Physics by the President of Poland, in recognition of his exceptional track record of international standing research and his role in developing the field of GaN-based optoelectronics in Poland.
