Sajeev John, OC, FRSC (born 1957) is a Professor of Physics at the University of Toronto and Canada Research Chair holder. He is known for his discovery of photonic crystals.
He received his bachelor's degree in physics in 1979 from the Massachusetts Institute of Technology and his Ph.D. in physics at Harvard University in 1984. His Ph.D. work at Harvard introduced the theory of classical wave localization and, in particular, the localization of light in three-dimensional strongly scattering dielectrics. From 1984 to 1986 he was a Natural Sciences and Engineering Research Council of Canada postdoctoral fellow at the University of Pennsylvania, as well as a laboratory consultant to the Corporate Research Science Laboratories of Exxon Research and Engineering from 1985 to 1989.
From 1986 to 1989 he was an assistant professor of physics at Princeton University. In 1987, while at Princeton he co-invented, along with Eli Yablonovitch, the concept of a new class of materials with a photonic band gap called photonic crystals. This provided a fuller explanation of his original conception (1984) of the localization of light. He was a laboratory consultant to Bell Communications Research (Red Bank, NJ) in 1989. In the fall of 1989 he joined the senior physics faculty at the University of Toronto. He has been a Principal Investigator for Photonics Research Ontario and is a fellow of the Canadian Institute for Advanced Research.
