• Russian Scientists Develop World's Smallest Blue Laser For Displays

  In collaboration with their colleagues from MIPT’s Center for Photonics and 2D Materials, scientists from ITMO University have devised the world's smallest laser that emits light in the blue spectrum. With a volume 13 times smaller than the wavelength of the produced light, it paves the way for the creation of a new generation of ultra-high-resolution displays and compact biomedical devices. The research is supported by grants from the Russian Science Foundation.

• “Combing” Light: ITMO Researchers Find Reliable and Fast Way to Transmit Data in Space

  A team of Russian scientists has suggested a simple way to increase the capacity and reliability of free-space optical communication. This is done by controlling the structure and composition of a “comb” made from vortex laser beams, with each beam functioning as a separate data transmission channel. The corresponding study was published in Nano Letters.

• ITMO Researchers Produce Artificial Optical Synapse for Enhanced AI Performance

  Scientists at ITMO University have developed an artificial optical synapse using a natural inspired semiconductor, copper exide, also known as tenorite. When exposed to laser radiation, the mineral’s crystals start to behave as biological synapses in the brain; they respond differently  to radiation based on the frequency of laser pulses, akin to synapses reacting to biologically active chemicals – neurotransmitters. The finding may open the way for next-gen processors that can imitate the function of biological neural networks; it can also accelerate AI calculations and training at lower energy costs. The results of the study were published in ACS Applied Materials & Interfaces.

• ITMO Researchers Learn to Quick Control Metasurfaces With Light

  A team of researchers from ITMO University, Polytechnic University of Milan (Italy), and the University of Brescia (Italy) have developed a new approach to control the properties of metasurfaces using laser radiation. The method allows scientists to switch optical states within a picosecond, which means that they can now transmit more data in less time and build a photonic computer and more accurate medical sensors. The results of the study are published in Light: Science & Applications.

• The Heat-Ray: How H.G. Wells Predicted Lasers

  H.G. Wells is a sci-fi writer who got a jaw-dropping share of the future right. Nearly 80% of technologies described in his writings have eventually come true: from automatic sliding doors to space travel. Among such is the laser, or the Heat-Ray as it’s called in The War of the Worlds. What is the Heat-Ray? How close was the futurist in his predictions? And how much science is there in sci-fi? Van Gulinyan, a laboratory assistant at ITMO’s Faculty of Physics, knows the answers.

• ITMO Researchers Use Hybrid Crystal to Enable Simultaneous Grayscale and Color Direct Laser Writing

  With the new material suggested by ITMO physicists, it will be possible to embed grayscale images into color ones during direct laser writing. The researchers were the first to use metal-organic frameworks for the purpose; these are optically transparent materials that can transform laser radiation. When subjected to it, the material’s structure changes, with color defects formed inside. Each such defect has a unique scattering spectrum, making metal-organic frameworks useful in producing uncloneable anti-counterfeit trademarks. The material is described in a paper published in Advanced Functional Materials.

• Power Without Electricity: Nanodevice For Optical Computers Developed at ITMO

  Physicists from ITMO and St. Petersburg Academic University have collaborated to develop a device that can be used as a transistor in optical computers – it can create an electric field in nanostructures without the use of any power sources. In the article published in Light: Science & Applications, the research team describes the theory behind it as well as the experiments they conducted on a nanoantenna to demonstrate the capacities of the new device.

• ITMO Scientists Develop Simple Method to Create Durable Anti-Fraud Trademarks

  ITMO University physicists collaborated with experts from Laser Center to develop a new production method for holographic anti-fraud trademarks. With the new technology, it is possible to print unique multicolor 3D holograms on any metal products to protect them from counterfeit. Apart from being highly durable, the trademarks can be made using minimal equipment. The developers claim that this method is cheaper and more secure than the conventional holographic stickers.

• Studying Attosecond Physics in Italy: ITMO Master’s Student Shares His Experience

  Petr Snetkov is one of ITMO’s talented young researchers: a Master’s student in the program Megascience Laser and Synchrotron Technologies and a senior engineer at the Center for Chemical Engineering. Recently, he had the opportunity to participate in the Erice Attosecond School “The Frontiers of Attosecond and Ultrafast X-ray Science,” held at the Ettore Majorana Foundation and the Centre for Scientific Culture in Italy. In this interview, we asked him all about this experience – and where you can find similar opportunities.
