Self Assembled Photonic Band Gap Symposium
Sunday and Monday April 7 & 8

Overview
Realization of the full potential of photonic bandgap crystals will require the concerted efforts of multidisciplinary research teams. We are organizing a two-day symposium that will bring together researchers working in this emerging field. Both self-organization and lithographic processing approaches are important ways to form patterned structures with the requisite dimensions and symmetry. This symposium will focus on methods employing self-assembly of inorganic and organic materials to form electromagnetic crystals. Topics of interest include: fabrication of optical scale photonic crystals, incorporation of semiconductor particles into thin film photonic crystals, template directed assembly, novel photonic crystal concepts, influence of various types of disorder on band structure, control of defects, processing for low cost, large area structures, and characterization of active devices such as lasers and displays. The symposium will cover a diverse range of subjects such as organic and inorganic synthesis, colloid chemistry, vapor deposition, electrochemistry, optical characterization, and theoretical computation and will thus attract chemists, physicists, materials scientists and chemical engineers.

Organization
The symposium to be a platform for dissemination of recent developments in the field of self-assembled photonic materials. By bringing researchers from a wide variety of backgrounds we wish to initiate dialogue and collaborations that will push the frontiers of this field. We would also like to invite researchers from other areas (especially graduate students and young faculty who are establishing their research directions) to participate in the symposium. We will therefore begin the symposium with three detailed tutorials. These lectures will cover the basic foundations necessary for participating in the symposium. The first tutorial, given by Bruce Garetz, will introduce the fundamental equations that describe the interaction between radiation and matter, and the physical phenomena that underlie the equations. The second lecture, given by David Pine, will build on the first lecture and discuss the propagation and scattering of light in periodic structures. Here we will introduce the formal connection between electronic band structure and the optical properties of periodic structures. The third lecture, given by Edwin Thomas, will provide a link between the developments in lectures 1 and 2 and the practical issues relating to the materials we seek to create. He will discuss methods for computation of band structure for 1D layers, 2D cylinders and various 3D bicontinuous cubic structures, basic approaches methods for measurement of photonic band structure, and potential applications of self assembled photonic crystals.

The tutorials will be followed by invited and contributed talks given by both senior researchers as well as graduate students. The list of speakers who have accepted our invitation are: Sanford Asher (University of Pittsburgh), Paul Braun (University of Illinois), Timothy Bunning (Wright Patterson Air Force Base), Noel Clark (University of Colorado), Samuel Jenekhe (University of Washington), Eric Kaler (University of Delaware), Geffory Ozin (University of Toronto), David Pine (University of California, Santa Barbara), Anthony Ryan (University of Sheffield), Samuel Stupp (Northwestern University, Pierre Wiltzius (Bell Labs, Lucent Technologies), Younan Xia (University of Washington).
