Creation of optical materials and photonic components using micro-
or nano-structuring to tailor the optical response of dielectrics
and metals in order to create synthetic materials with different or
improved optical properties

Photonic crystal fibers (PCF) as a platform technology
for a range of new applications

The focus of Research Area C is to tailor the optical response by
micro- or nano-structuring so as to create synthetic materials with
radically different or improved optical properties. These synthetic
materials take the form of photonic crystals (λ scale features) and
metamaterials (sub-λ scale features), and are made by texturing
available substances and building composites from nanometer-sized
colloidal particles. The aim is to control the propagation of light and
its interactions with matter in new ways (e.g. extreme refractive
indices, low group velocities, high anisotropy, evanescent field
focusing, electromagnetic invisibility), improving existing devices and
realizing completely new ones (e.g. super-resolution imaging systems).
On the micro-structured scale, the emphasis will be on photonic crystal
fibers (PCF), which are distinguished by a transverse two-dimensional
“crystal” lattice of repeating units made of hollow channels that run
axially along the fiber. Compared to conventional fibers, the modal
phase index, dispersion, window of transparency, nonlinearity, and
birefringence can be tailored over wide parameter ranges. PCFs form a
“platform technology” for many new applications in the study of e.g. the
optical properties of ionic liquids, optical sensors, biomedical
devices, and laser-machining. A related goal is the optical manipulation
and characterization of nm-sized particles. Laser light will be used to
trap, manipulate, and optically characterize living cells, vesicles,
colloids, and metallic clusters, for example, both in free space and
inside hollow-core PCFs.
