Norwood's research portfolio consists of work ranging from nanoscale electro-optic modulators to 40 square meter hybrid solar energy systems. Schematic showing basic approach to a high efficiency solar panel. In fact, it shows such promise that it was awarded a $1.82 million grant from the National Institutes of Health. This technology could be useful in medical diagnostics, environmental health monitoring and detecting chemical threats, said Judith Su, Ph.D., assistant professor of optical sciences and biomedical engineering. But perhaps the best part? They may be helpful in detecting and treating COVID-19, cancer and scores of other harmful or deadly contaminants.

Judith Su, an assistant professor of biomedical engineering and optical sciences, runs the UArizona Little Sensor Lab, where researchers are finding ways to use a one-of-a-kind technology to address some of the medical community's most pressing problems. To review past updates, see the Photonics Research Updates Archive page. Professor Masud Mansuripur, the college's Chair of Optical Data Storage, recently has provoked considerable controversy by reminding the physics community that the commonly used Lorentz force law for charged particle motion is not relativistically invariant when applied to magnetic materials in the presence of an electric field the suggested remedy is to return to an alternative force law proposed by Albert Einstein in 1908. The re-writable hologram of Albert Einstein shown as a 2-D figure was created with state-of-the-art technology developed by our group. Communications, displays, medicine, manufacturing and imaging are just a few applications. New areas are constantly explored by our nine faculty in the specialty, as photonics becomes more pervasive in our lives. Research in photonics at the College of Optical Sciences ranges in scope from fundamentally new tools, such as small-footprint, high-throughput multiphoton microscopes, through exceptionally high-power semiconductor lasers, to components and systems for next-generation optical networks for both the Internet and data centers, and into consumer equipment like 3-D displays.
