Dr. Mafi heads UWM’s Photonics Research Group which is on cutting edge of photonics.  The main concentration is on the nonlinear and quantum aspects of guided-wave optics. Dr. Mafi believes guided-wave optics, whether in the form of optical fibers, or as plasmonic and silicon nano-waveguides, will continue to remain a fundamental platform in device applications.
