Free-Space Signal Processing with Organic Third-Order
Nonlinear Optical Materials |
|
Highly nonlinear conjugated organic materials such as
polyacetylene derivatives are being developed for use in free
space optical information processing. These materials offer
potential for high temporal bandwidth and picojoule to femtojoule
switching energy for optical image or signal processing. In this
project, conjugated polymers will be studied in device
geometries that are very sensitive to optically induced index
changes and their signal processing capabilities will be
characterized.
