Dennis T. Norton Jr. received his B.S. degree in Physics and Mathematics from Western Illinois University, Macomb, IL, in 2007. He received his Ph.D. degree in physics from the University of Iowa, in 2013. There he carried out research on the development of infrared light-emitting diodes based on type-II InAs/GaSb superlattice active regions. While pursuing his Ph.D., he worked as a research scientist for ASL Analytical, Coralville, IA, developing an infrared spectroscopy system for monitoring bioreactor processes in real-time. There he fabricated and characterized infrared detectors, superluminescent diodes, and tunable lasers based on III-V materials. He is currently a System Engineer at Santa Barbara Infrared, Santa Barbara, CA, where he is developing infrared scene projectors based on multiple-quantum well and interband cascade infrared light-emitting diode arrays. Prior to joining Santa Barbara Infrared, Dr. Norton was a Research Associate of the National Research Council at Eglin Air Force Base, FL. There he developed infrared light-emitting diodes with spectral emission covering the entire 3–5μ waveband, and established an infrared optoelectronic characterization, experimental test-bed to support characterization of both infrared emitters and detectors.
