Professor Stephen M. Kuebler Department of Chemistry and CREOL, The College of Optics and Photonics University of Central Florida Nanophotonic Materials Group website Tuesday, March 3, 2020 - 3:30pm Chemistry Building, Room 430 Special Information: *please note time and room change* Departmental Colloquium Nanophotonics involves the development of fundamental science, materials, and applications that leverage the interaction of light and matter on the nanometer to micrometer length scales. This growing and highly interdisciplinary field involves chemistry, materials science, physics, engineering, and bio-science. In this presentation Dr. Kuebler will introduce the field of nanophotonics and describe some work done by his group in this area. The talk will focus on the development of chemistries, materials and processes for multi-photon lithography (MPL) and show how they have used MPL to create functional nanophotonic devices. He will also show how his team has used MPL to create micro-optics on the tip of optical fibers and spatially-variant photonic crystals that can bend light through extremely sharp turns. These devices can be used to create new integrated photonic devices, including low-profile sensors. Related Publications 1. C. M. Schwarz, C. Grabill, G. D. Richardson, S. Labh, B. Gleason, C.
