M. Saif Islam, Professor and Chair
Research Focus: Professor Islam’s work has covered a broad variety of topics: ultra-fast optoelectronics, materials and devices for harsh environments, synthesis of low-dimensional semiconductor and oxide nano-structures, and their applications in devices, ultra-sensitive novel sensors, detectors, circuits and systems; and fiber optical and RF photonic communication links. His group was the first to demonstrate light-bending and photon-trapping slow light photodetector that capitalizes on the enhanced photon-material interaction to dramatically increase the light absorption capabilities of ultra-fast semiconductors that are weak in absorption characteristics. He was the first to demonstrate the velocity-matched distributed balanced photodetectors with a record high linear photocurrents and an ultra-fast response. Dr. Islam developed the technique for generating ultra-smooth metal surfaces for interfacing molecular electronic devices that improved the yield of molecular switching devices fabricated with self-assembled monolayers (SAMs) of molecules. Such metal films also contributed to the smoothest superlens ever reported. His group developed a technique for dynamically switching between positive and negative permeability of metamaterials by photoconductive coupling. He reported the first semiconductor nanowire bridging technique which effectively addresses the challenges of interfacing and integrating one-dimensional semiconductors in nanoelectronic and nanophotonic devices.
