Professor of Physics
Ph.D. Physics – City College of New York (CCNY) 1981
Dr. Johnson was a Member of the Technical Staff in the Quantum Physics and Electronics Research Dept. and a Distinguished Member of the Technical Staff in the Photonic Circuits Research Dept. at AT&T Bell Laboratories for 14 years prior to joining the New Jersey Institute of Technology (NJIT) in 1995. At NJIT he was Chairperson and Distinguished Professor of Physics for 8 years prior to joining the UMBC Physics Dept. in August 2003.
Dr. Johnson’s general area of research is in ultrafast optical and optoelectronic phenomena. He has nearly 80 refereed publications, 2 book chapters and 4 US patents. His current research interests include the ultrafast photophysics and nonlinear optical properties of bulk, nanostructured and quantum well semiconductor structures, ultrashort pulse propagation in fibers and high-speed lightwave systems.
