  • New Discovery Makes Cheap, Compact Lasers Possible

    Researchers from ITMO have demonstrated a novel technique for generation of laser radiation that utilizes perovskite metasurfaces. The solution will pave the way for next-gen lasers that are less than 100 nm thick and require significantly less energy. The invention can be incorporated into compact photonic chips for light control or used as an intense light source in medicine (e.g., for tissue or blood diagnostics), materials processing, astronomy, and other fields. The results of this study were published in the journal Advanced Functional Materials.

  • ITMO Researchers Twist Particles Using Quantum Entanglement

    Twisted particles have found their applications in many fields, such as optomechanics, biology, astrophysics, as well as quantum optics, information science, and communications, where, for instance, they can be used to increase data capacity. However, as these particles are primarily obtained through diffraction gratings, they can’t yet be used for experiments in nuclear and particle physics given the high energies of particles used in contemporary colliders. As a solution to this problem, physicists from ITMO University have suggested a method of obtaining such particles using the so-called generalized measurements, without relying on any special equipment. Their research was supported by a Russian Science Foundation grant, with its results published in The European Physical Journal C (Particles and Fields).
