C2.2 – Interaction of ordered excitonic matter with metasurfaces
Principle Investigator: Prof. Klas Lindfors
During the first cohort of TIDE, the focus was on exploring the order of merocyanine molecule thin films and its influence on the optical properties of the material. We studied in detail the light-matter interaction and in particular explored the strong-coupling regime.
In the second cohort of TIDE, we want to focus on light-matter interactions in metasurfaces and individual plasmonic nanoantennas. Metasurfaces are ordered two-dimensional periodic structures of metallic or dielectric nanostructures. The properties of the unit cell of the surface, the metamolecule, together with the symmetry of the periodic array allow controlling the optical response of the surface in unprecedented ways. Within the project we will explore realizing active, switchable metasurfaces and their nonlinear optical properties. Emphasis is placed on studying how the order and orientation of the organic molecules and their spatial distribution influences and can be used to engineer the properties of the system. We work together with projects A1.2 and A2.2 on novel organic semiconductors, project B1.2 on templating, and project E3.2 on modeling the properties of templated thin films.
The ideal candidate has a master’s degree in physical chemistry or condensed matter physics with emphasis on optics or optical spectroscopy. Familiarity with nanofabrication is an advantage. We offer state-of-the art nanofabrication facilities for nanostructure fabrication and a comprehensive set of optical microspectroscopy methods for sample characterization.
