Dr. B.G.Potter is a Professor of Material Science and Engineering in the University of Arizona. Research activity within Dr. Potter's group is centered on the synthesis and study of glass, ceramic, and molecular hybrid materials for photonic and electronic applications. Active research and ongoing programs include: optically driven molecular assembly strategies, nanostructured photovoltaic ener...

We exploit theoretically a magneto-controlled nonlinear optical material which contains ferromagnetic nanoparticles with a non-magnetic metallic nonlinear shell in a host fluid. Such an optical material can have anisotropic linear and nonlinear optical properties and a giant enhancement of nonlinearity, as well as an attractive figure of merit.

Reflectins are a unique group of structural proteins involved in dynamic optical systems in cephalopods that modulate incident light or bioluminescence. We describe cloning, structural characterization, and optical properties of a reflectinbased domain, refCBA, from reflectin 1a of Hawaiian bobtail squid, Euprymna scolopes. Thin films created from the recombinant protein refCBA display interest...

We use optical, photocurrent and photothermal deflection spectroscopies to study defects in microcrystalline silicon Ž . mc-Si thin films and diamond layers. Enhanced light absorption in mc-Si films and solar cells is due to several contributions: light scattering, change in the optical transition probability for strained and surface atoms and residual Ž y1 amorphous fraction. Low defect densit...

Well-characterized solid-state laser materials are evaluated for performance in optical refrigeration as well as radiation-balanced laser systems. New figures-of-merit are developed and applied to ytterbium-doped materials. Superior performance is predicted for high-cross-section tungstate materials. Photothermal deflection experiments on samples of Yb3+-doped KGd(WO4)2 confirm anti-Stokes fluo...
