Materials and Structures
The development of materials and structures is paramount for light-based technologies. The continuous study and development new materials and structures, linked with the fundamental research on light field control and with the integrated components and devices developed in and applied in quantum technologies and other applied research on photonics. As the result of the research conducted so far, new topics such as 2D, perovskite, and up-conversion and down-conversion materials are added to this research focus area. Novel structures are also targeted such as metasurfaces with enhanced linear and nonlinear optical responses for sensing and imaging purposes, artificial atoms and molecules (e.g. composed of gold nanoclusters, vacancy centers in diamond or single-defects in 2D materials) for light emission, and tandem structures with hybrid materials for integrated solar cells. Incorporating hybrid advanced materials with novel structures opens up new solutions for energy-efficient, compact, and low-cost applications.
