Joseph W. Haus is the Director of the Electro-Optics Program and the LADAR and Optical Communications Institute at the University of Dayton. His active research is devoted to linear and nonlinear optical properties of materials, fiber lasers, and laser radar (also called ladar) coherent imaging techniques. Haus is a fellow of the American Physical Society, the Optical Society of America and the SPIE and has nearly 200 publications in refereed journals. He is on the editorial board of three international journals and he serves in several conference committees, including the International Conference on Nanophotonics held annually in China. He received a Ph.D. from Catholic University of America in 1975 and worked at several institutes and universities in the U.S., Germany and Japan prior to his appointment at UD. He has been a frequent visitor to Puebla, Mexico with collaborations extending more than a decade.

RESUMEN:

The word metamaterial conjures visions of invisibility cloaks and optical black holes in the public's imagination. The subject has grown from a singular paper by Sir John Pendry published in 2000 that stimulated research activities around the globe. This talk provides a foundation for understanding the bizarre optical properties of metamamaterials. Furthermore, creating metamaterials in the visible region poses enormous nanofabrication challenges, but there are other avenues to explore available materials. I will show how designing and fabricating nanostructured layered or nanoparticle composite materials can mimic some exotic metamaterial properties. This talk also extends beyond the regime of linear optics to expose fundamental aspects of nonlinear wave interactions in materials that are equally astonishing.
