Russian scientists from Kazan Federal University and their colleagues from Purdue University in the USA have laid the foundations for a new scientific field. It has been named non-local photonics. The researchers discovered an unusual property in a new class of materials — dual crystal-liquid systems.
It turned out that these materials exhibit an anomalous increase in refraction when a laser beam is directed at them. During their synthesis using self-assembly of nanoparticles or using thermo-optical annealing of amorphous films, the materials can overcome the fundamental limitations of the refractive index of the medium.
A high refractive index opens up unique opportunities in optoelectronics and quantum computing.
The research was carried out with the help of a state subsidy under a state assignment in a laboratory created as part of the "Priority 2030" program.
