Previous Experience

Dr. Johnson joined the Physics Department in 2003 after 8 years as the chairperson & Distinguished Professor of Applied Physics, and Professor of Electrical & Computer Engineering at the New Jersey Institute of Technology (NJIT), Newark, NJ. Prior to that 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 of the Photonic Circuits Research Dept. at AT&T Bell Laboratories, Holmdel, NJ.

Professional Interests

I work in the general area of ultrafast optics and optoelectronics - the ultrafast photophysics and nonlinear optical properties of bulk, nanoclustered, and quantum well semiconductor structures, ultrashort pulse propagation in fibers and high-speed lightwave systems and over 70 refereed publications, 2 book chapters and 4 US patents.
