Kurzbeschreibung
(Englisch)
|
The infiltration of photonic crystal structures with different materials provides a great potential for dynamic manipulation of optical properties at length scales in the order of the wavelength of light with applications ranging from tunable integrated optical circuits to highly sensitive sensor for bio or chemical detection. This proposal will focus on the infiltration of two different materials into high-Q resonant cavity structures. First, a dichroic dye in a liquid crystal host will be infiltrated in order to study the physics of the infiltration and to investigate the expected switching properties. Second, issues such as inhibited and enhanced fluorescence emission for specific bands will be studied by infiltrating a fluorescent dye into the cavity structure. The investigation of the optical interactions with different infiltrated materials will open up new possibilities for applications in domains such as biology, chemistry and medicine.

Abstract
(Englisch)

The infiltration of photonic crystal structures with different materials provides a great potential for dynamic manipulation of optical properties at length scales in the order of the wavelength of light with applications ranging from tunable integrated optical circuits to highly sensitive sensor for bio or chemical detection. This project is focused on the infiltration of two different materials into high-Q resonant cavity structures. It was planned that a dichroic dye in a liquid crystal host will be infiltrated in order to study the physics of the infiltration and to investigate the expected switching properties. For this purpose, different photonic structures have been investigated numerically and their fabrication has been studied in detail. Test elements for further characterization have been realized. The optical characterization is still missing at this point. We expect that the investigation of the optical interactions with different infiltrated materials will open up new possibilities for applications in domains such as biology, chemistry and medicine.
