Polariton Physics

This book offers an overview of polariton Bose–Einstein condensation and the emerging field of polaritonics, providing insights into the necessary theoretical basics, technological aspects and experimental studies in this fascinating field of science. Following a summary of theoretical considerations, it guides readers through the rich physics of polariton systems, shedding light on the concept of the polariton laser, polariton microcavities, and the technical realization of optoelectronic devices with polaritonic emissions, before discussing the role of external fields used for the manipulation and control of exciton–polaritons. A glossary provides simplified summaries of the most frequently discussed topics, allowing readers to quickly familiarize themselves with the content.The book pursues an uncomplicated and intuitive approach to the topics covered, while also providing a brief outlook on current and future work. Its straightforward content will make it accessible to a broad readership, ranging from research fellows, lecturers and students to interested science and engineering professionals in the interdisciplinary domains of nanotechnology, photonics, materials sciences and quantum physics.

Dr. Arash Rahimi-Iman is a lecturer and young group leader at the Philipps-Universität Marburg, Germany. He received his Ph.D. from the Faculty of Physics at the University of Würzburg, Germany, in 2013, where he worked on the development and demonstration of an electrically-pumped polariton laser. Currently, he is a principal investigator of several projects in the field of semiconductor lasers, two-dimensional materials and polariton physics at the Department of Physics and the Materials Sciences Center in Marburg. The focus of his work is on optical spectroscopy of nanostructured systems consisting of quantum wells, quantum dots, or novel semiconductor materials and on the development and study of semiconductor lasers. During the last decade, he has authored and co-authored over 100 publications in various science journals, frequently presented at international conferences, and has refereed articles for renowned publishers. In addition, he has acted as a visiting lecturer and symposium co-organizer at the Zhejiang University, China. Furthermore, Dr. Rahimi-Iman supports the academic endeavours in Marburg as a member of the Steering Committee of the Materials Science Center, as well as of the Steering Committee of the Marburg Research Academy, and as a Faculty Board member of the Physics Department in Marburg.
