Ultrafast detection, a technique that uses light to detect extremely fast phenomena, is the main research interest at the Photonics Lab, which is directed by Dr. Hossein Asghari. This technology has applications in medicine, telecommunications and aerospace/defense. For example, it can quickly sort through millions of cells in human blood to find the few that might be cancerous, greatly enhance the speed of a slow oscilloscope so it can capture much faster events, and capture the vibrations of objects moving as fast as million miles per hour.
He has already commercialized this technology to make it more accessible for other researchers in industry and academia. Students across disciplines can bring ideas for projects in ultrafast detection to his lab and publish papers in high-impact international journals and conferences. Other applications of interest include real-time optical signal characterization and wideband data conversion.
