• New Study from ITMO: Waveguides Made Invisible to Each Other in 2D Lattice

  Physicists from ITMO and University of Chile have demonstrated mutual invisibility in a waveguide lattice for the first time. With this alignment, adjacent waveguides don’t exchange light: upon entering the lattice, light doesn’t scatter and instead remains a limited area. Conducted with support from the Russian Science Foundation grant No. 24-72-10069, the study was described in a paper published in Nano Letters.

• ITMO Scientists Create Improved Optical Module for AR Devices

  Researchers from ITMO have used volume holography to develop an optical module that is resistant to chemical damage, physical impact, and extreme temperatures. This module, called a combiner, can be used to create industrial-purpose AR glasses or to project interfaces directly onto the windshields of cars and airplanes. Unlike its counterparts, the device is single-layered, which makes it lighter and prevents glare. The project is supported by the Priority 2030 program.

• Picture of the Week: Lithium Niobate Crystal

  In the image, you can see a fragment of a lithium niobate crystal; such crystals are used in integrated optical waveguides. Optical modulators based on such structures are applied in fiber-optic gyroscopes.

• ITMO Researchers Win Grant for Development of Smart Glasses Components

  The scientists will develop a method for the development of waveguides invisible to the naked eye and which will make it possible to transmit images onto transparent glass and polymer surfaces. It will also be possible to use the same technology to create sensors useful in the production of protective eyewear for workers in hazardous occupations.
