Gains are derived from nanowires and light trapping for better energy conversion.
Sajeev John is a University Professor at the University of Toronto and Government of Canada Research Chair holder. He received his bachelor’s degree in physics in 1979 from the Massachusetts Institute of Technology and his PhD in physics at Harvard in 1984. His PhD work introduced the theory of classical wave localization and in particular the localization of light in three-dimensional strongly scattering dielectrics.
His groundbreaking work in the field of light localization that enables light to be controlled at the microscopic level has earned him an international reputation. He is a pioneering theoretician in photonic band gap (PBG) materials. This new class of optical materials presents exciting possibilities in the fields of physics, chemistry, engineering and medicine. PBG materials could eventually be used for optical communications/information processing, clinical medicine, lighting and solar energy harvesting.
John has received numerous awards, including the King Faisal International Prize in Science (2001), the IEEE Nanotechnology Pioneer Award (2008), and the Killam Prize in Natural Sciences (2014) from the Canada Council for the Arts. He is a Fellow of the American Physical Society, OSA, the Royal Society of Canada, and a member of the Max-Planck Society of Germany.
