Non-linear Physics

The Experimental Photonics group at the Nonlinear Physics Centre conducts research in the areas of Nano-, bio- and quantum photonics. The focus of our research activities is the development of dielectric and metallic metasurfaces. These are artificial flat nanomaterials with unique optical properties designed by nano-structuring of the surfaces. Such metasurfaces allowed us to manipulate optical beams and wavefronts with great efficiency, thus designing flat optical elements, including lenses, holograms and vortex plates.

Based on this unique platform, the group is working on new types of applications in bio nano and quantum technologies. The research projects in the group include:

  • the development of highly nonlinear metasurfaces for night vision application (see image),
  • the development of efficient devices for wavefront control,
  • the development of highly sensitive biosensors,
  • the development of tunable metasurfaces for autonomous vehicles,
  • enhancement of light emission for advanced displays, and
  • research on novel quantum devices for generation and manipulation of quantum light.

In many of these projects, we work closely with other groups at the NLPC, including the theoretical photonics group, led by A/Prof. Andrey Sukhorukov, the THz and microwave metamaterials group, led by A/Prof. Ilya Shadrivov, the theoretical plasmonic and nanophotonics group, led by A/Prof. Andrey Miroshnichenko and the Exciton-polariton group, led by A/Prof. Elena Ostrovskaya.
