Molecular Engineering for Optoelectronics

Objectif

Optics and microelectronics will increasingly co-exist in the form of active or passive optical interconnections between microelectronic chips, mixed optoelectronic devices and purely optical devices as part of mixed optoelectronic systems. Furthermore, o rganic electro-optic and non-linear optical materials can find application in logic elements, large band modulators, tuneable parametric amplifiers and emitters in transmission and signal-processing systems. The objective of this project was to provide a basis for the essential knowledge needed for the development of molecular-based IT devices.
The objective of this project was to provide a basis for the essential knowledge needed for the development of molecular based information technology (IT) devices.

The progress achieved includes the following:
assembly of a reliable code for the prediction of the molecular beta coefficient from atomic coordinates;
synthesis and demonstration of properties in pyrazoline and polyene molecules;
development of an efficient routine for searching the crystallographic databases for active molecules of suitable symmetry for x {2};
knowledge of the effects of hydrogen bonding on hyperpolarisabilities of molecules;
methodology to calculate the static polarisability and hyperpolarisabilities of molecules;
methodology to calculate the static polarisability of infinite regular polymers;
identification of various bonding patterns capable of high electronic responses;
setting up of relevant facilities for the characterisation of beta and X {2};
synthesis and dipping of a range of tailor made molecules from which high second harmonic generation has been observed;
attachment of active molecules to a polyester backbone to give liquid crystal phases;
quantification of the factors which govern the lattice symmetry for the polar molecules of interest;
successes in Langmuir-Blodgett and liquid crystal techniques;
knowledge of deposition conditions, structural properties and nonlinear properties;
development of ultrafast ultrasensitive spectroscopic or infrared (IR) signal processing tools (PASS).
The progress achieved includes the following:
-assembly of a reliable code for the prediction of the molecular beta coefficient from atomic coordinates
-synthesis and demonstration of properties in pyrazoline and polyene molecules predicted from the above
-development of an efficient routine for searching the crystallographic databases for active molecules of suitable symmetry forX(2)
-knowledge of the effects of hydrogen bonding on hyperpolarisability
-methodology to calculate the static polarisability and hyperpolarisabilities of molecules within the Routine Hartree Fock (RHFSum Over States and RHFFinite Field frameworks)
-methodology to calculate the static polarisability of infinite regular polymers within the RHFSum Over States framework
-identification of various bonding patterns capable of high electronic responses.
-setting up of relevant facilities for the characterisation of beta and X(2).
-synthesis and dipping of a range of tailor-made molecules from which high second harmonic generation has been observed
-attachment of active molecules to a polyester backbone to give liquid crystal phases; addition of beta has been obtained by aligning under an electric field applied above Tg and cooling to the immobile phase vectorial
-quantification of the factors which govern the lattice symmetry for the polar molecules of interest is now well underway, and a number of effective routines have been written to model crystallisation
-successes in Langmuir-Blodgett and liquid crystal techniques were motivated by the desire to construct planar waveguide arrays for integrated optics; LangmuirBlodgett technology has benefited highly from this collaboration, and knowledge of depositionconditions, structural properties and nonlinear properties, starting from almost nil at the onset of the project, reached a level where technological follow-ups are planned
-development of ultrafast ultrasensitive spectroscopic or IRsignal processing tools(PASS).
The achievements of project 443 mark a significant step towards the development of devices for signal processing and optical computing. However, other specific aspects, such as packaging, electrode deposition, integration of devices onto arrays, etc, needto be addressed in parallel with the material studies before such devices can be realised.
