Welcome
to the homepage of the Organic Optoelectronics Laboratory in the
Physics Department at Case Western Reserve University.
Our research centers on the optical and electronic properties of
organic materials. The emphasis is on understanding the physical
mechanisms involved in the application of organic materials to
optoelectronic technology. We are interested mainly in the properties
of organic molecules, liquid
crystals and polymers. All of our projects are interdisciplinary in
nature, involving chemists from various institutions.
The principal optical experiments in the group include z-scan,
pump-probe third order nonlinear optics, coherent second harmonic and
third harmonic generation, hyper-Rayleigh scattering, Pockels effect,
various waveguiding experiments, and photorefractive 4-wave mixing and
2-beam coupling. We use CW and pulsed lasers in these experiments. We
also measure the transport properties of carriers in these materials
using photoconductivity and dark conductivity measurements. We also
fabricate prototype devices that help us understand the capability of
new materials.
Our current projects include the multilayer polymers for photonics as
part of the CLiPS center, 2-dimensional dynamic photonic crystals,
chiral media for photonics, and transport properties of liquid crystal
and polymer materials. The applications toward which these studies are
aimed include solar cells ( photovoltaic devices ), optical switches,
lasers and lighting, display technology and thin film transistors.
