Optical Sensor Technology for Optics, Information Technology and Nanotechnology

Dear Colleagues,

In the last few decades, optical sensor technology has attracted considerable attention for employing structured singular beams and devices on their basis in different areas. An important role here is played by advances in technologies of metamaterials, nanophotonics, and fiber optics, as well as the development of methods for measuring mode spectra in complex vortex beams, the latest advances in digital big data processing, and recovering singular beams subject to external perturbations. Therefore, in this Special Issue, we welcome the latest findings from research, ongoing projects, and review articles that can provide readers with information on current research trends and solutions in optical sensor technology development on the basis of structured vortex beams. In addition, a few highly qualified papers selected and extended from the 7th International Conference on Information Technology and Nanotechnology (ITNT 2021) and the International Conference “Digital Singular Optics: Applications and Fundamentals” (DSO'2021) will be included in this Special Issue. The 7th International Conference on Information Technology and Nanotechnology (ITNT 2021) will be held 20–24 September 2021, in Samara, Russia (http://itnt-conf.org/). The International Conference “Digital Singular Optics: Applications and Fundamentals” (DSO'2021) will be held 6–10 September 2021, in Yalta, Crimea (http://singular-optics.org/en/).

The 7th International Conference on Information Technology and Nanotechnology (ITNT 2021) is intended to provide a forum for leading scientists from all over the world to discuss the latest advances in basic and applied research in the field of Information Technology and Nanotechnology, attract young people to advanced scientific research, and share the latest trends in training and research programs for future ITNT specialists. Within the framework of the 7th International Conference on Information Technology and Nanotechnology (ITNT-2021), the Youth School will be held. At the Youth School, young researchers, postgraduate students, and senior students will become acquainted with the scientific achievements in the Conference topics and also with unique laboratories and equipment of the Samara University.

The International Conference “Digital Singular Optics: Applications and Fundamentals” (DSO'2021) is intended to discuss new digital approaches and achievements in the area of singular optics, advances in the development of multifunctional systems and devices, as well as in transmission, storage, and information processing in fiber-optic networks. The approaches of singular optics (including fiber and nonlinear optics and their applications) promote the improvement of optical digital technology. That is why this conference is a unique opportunity to shed light on new standards and digital concepts concerning the physics of phase and vector singularities. The conference plans to present the latest achievements in the field of trapping, transportation, and structuring of microparticles in nanotechnological processes, the use of singular beams in optical cryptography, in optical transmission and information processing systems, as well as conceptual problems associated with key issues in information optics. The International Conference “Digital Singular Optics: Applications and Fundamentals” (DSO'2021) is an international conference for scientists and engineers, researchers and consultants, theoreticians, and practitioners in the fields of advanced optical research, namely, singular optics and related sciences.
