Dalton, University of Washington, DMR 0551020 R&D ACHIEVEMENT: Electrostatic interactions between the dipole moments of guest and host chromophores in binary chromophore glasses lead to factor of 3 enhancement in electro-optic activity. Laser-assisted poling produces a Bessel (2-D)-like alignment of the host lattice leads to a factor of 2.5 further enhancement of the guest chromophore acentric order. New analytical instrumentation has been developed and binary chromophore glasses provide a test bed for the quantitative investigation of intermolecular interactions. Electro-optic activity is shown for both electric field poling (blue) and laser-assisted electric-field poling (red) of a BCOG based on a DR1-PMMA polymer host. Modification of a Teng-Man ellipsometer to carry out laser-assisted poling is shown below.

3. Development of Synthesis, Processing and Characterization Techniques for Next Generation Electroactive Materials Larry R. Dalton, University of Washington, DMR 0551020 BROADER IMPACTS:Diversity enhancement activities include serving on (and chairing) the External Advisory Boards of Norfolk State University (NSU) and Alabama A&M University (AAMU). Education and diversity enhancement activities also include assisting NSU in development of their first Ph.D. program in Materials Science and Engineering and assisting AAMU implementing workshops on sensor science and technology. Technology has been transferred to a number of universities, Federal laboratories, and industries and has motivated the formation of a new company AES. Technology Transfer: ►Graduate students worked with Boeing to integrate organic EO materials into silicon photonic optical circuitry and develop chipscale information management (reconfigurable optical add/drop multiplexer devices, ROADMs). ►EO materials were transferred to Lumera, Inc. and were used to fabricate high bandwidth Mach Zehnder modulators exhibiting a drive voltage of 0.4 V. ►Dalton group graduate students co-found Advanced Electroluminescence Systems (AES) based on intellectual property created by the Dalton group ►Produced several encyclopedia reference chapters on nonlinear optics ►Lectured at major corporations (Intel, Corning, Ciba, etc.) considering R&D on electro-optics ►Delivered tutorial on sensor technology at a special workshop organized by the Institute for Defense Analyses Education, Knowledge Transfer, and Diversity Enhancement: ►Lectured in the ACS Summer School on Optical, Photonic, and Electronic Materials held at Central Florida University ►Worked Norfolk State University to implement the University’s first Ph.D. program in Science & Engineering ►Developed a reference text (CRC Press) with NSU faculty ►Mentored undergraduate (including from Seattle area community colleges) and Seattle area high school students ►Lectured before Seattle area business groups and helped form the Seattle Nano-Photonics Initiative to promote development of photonic based technologies in the Seattle area (Initiative will be managed by the Seattle Technology Alliance)
