Abstract:

Abstract:  Major breakthroughs in photonics have often occurred when superb materials science is coupled with elegant and efficient device design/fabrication.  Silica-based optical fiber, the semiconductor laser, the erbium doped fiber amplifier and the silica-on-silicon arrayed waveguide grating router are several notable examples of this phenomena.  State-of-the-art photonics now requires the development of ever-higher degrees of integration, placing stringent demands on photonic materials technology, which ultimately must be suitable for the new field of nanophotonics.  In parallel with these developments, the field of optical polymer nanocomposites (PNC) has emerged thanks to considerable advances in optical polymer materials, nanoparticle synthesis, nanoparticle functionalization and dispersion techniques.  Optical PNCs have the potential to fulfill a broad range of photonic functions ranging from compact, narrowband filters, to electro-optical modulation at hundreds of GHz.  To accomplish this, a clear understanding of optical polymer and nanoparticle properties is required, as well as an ability to effectively model and predict the properties of the PNC, and finally align these properties with the photonics engineering problem at hand.  We will discuss our recent work on optical PNCs, including PNC infiltrated silicon photonic crystals, polymer/InP nanowire composites, and magneto-optic PNCs.
