Objectives and Approach

Future optical processing and computing systems will require new materials exhibiting faster and more efficient non-linear optical properties than those presently available. The purpose of this project was to exploit the vast potential of organic molecular and polymeric materials for applications such as frequency conversion, parametric amplification and emission, optical bistability, electro-optic modulation, real-time holography and beam steering.

The aim of the project was basically twofold: firstly, it aimed to enlarge the exploration of candidate materials for non-linear optical devices. This would allow full advantage to be taken of the virtually unlimited possibilities of modern organic synthesis and require modelling and synthesis capabilities well represented in the consortium. Secondly, organic molecules were to be adequately shaped into materials, either in bulk or thin-film configurations, so as to be further incorporated in devices meeting the specifications of advanced optical information processing systems, both in terms of efficiency (essentially large bandwidth, low attenuation losses, low driving voltage or optical pump power) and long-term stability.

Two demonstrator devices were expected by the end of the project:
