• Researchers Note Topological Effects in New Waveguide Metamaterial

  A novel waveguide-based metamaterial, suggested by physicists from ITMO University and their colleagues from University of Chile, has been shown to exhibit topological states. Upon contact with the edge of a sample, the light that passes through the lattice is nearly never distributed inside the structure, unlike in traditional waveguide gratings. The findings were published in Nano Letters.

• Optical Innovations: ITMO Researchers Create Controllable On-Chip Topological States

  A research team featuring scientists from ITMO University and the City University of New York has successfully created controllable topological states that can be selectively excited on a silicon chip. This is the first time that such an effect was induced in the infrared range and inside a structure just a few microns in size. As proved in the article published in Nano Letters, the flexible control mechanism, as well as its on-chip implementation, can serve as a foundation for disorder-robust optical microchips.

• ITMO Scientists Find a Way to Reconfigure Topological States of Light

  A research team from ITMO University, Australian National University, and Jilin University has provided experimental proof of the conjecture that topological states of light can be produced not only by influencing the crystal lattice geometry but also by changing the shape of the meta-atoms and their mutual orientation. Moreover, the new approach helps change the position and the degree of light localization in real time.
