Sharon Weiss Receives NSF Award for Waveguide Research
Sharon M. Weiss, PhD, assistant professor of electrical engineering and physics at Vanderbilt University, will receive $400,000 over five years under a National Science Foundation (NSF) Faculty Early Career Development Award. The CAREER Award will support Weiss' efforts to achieve faster and more accurate detection of biological and

chemical materials by using portable porous-silicon waveguides. Weiss is investigating methods to achieve more sensitive detection of biomolecules in less time by using a sensor made from porous silicon, a material with billions of tiny nanometer-sized holes (1000 times smaller than the thickness of a human hair). “Accurate and reliable detection of biological and chemical materials is essential for improved medical diagnostics, environmental monitoring, and homeland security,” she said. “The extremely large surface area of porous silicon allows it to capture large numbers of biomolecules. By evaluating how light interacts with the silicon, we can detect the presence of trace amounts of biological material. Porous silicon sensors, made in our photonic crystals laboratory, have been used to identify specific DNA sequences and we will design them to detect various toxins and viruses in the near future.” Weiss, who holds one patent and has two pending, joined the Vanderbilt faculty in 2005. She received her BS, MS and PhD in optics from the Institute of Optics at the University of Rochester.
- The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
