A new prize honors the late Canadian physicist and 1994 Nobel laureate Bertram Brockhouse. The first recipients of the prize, which recognizes outstanding research by interdisciplinary teams of scientists, are Sajeev John and Geoffrey Ozin, both of the University of Toronto.
Together, John, a theoretical physicist, and Ozin, a materials chemist, design and make crystals that trap light. An early joint creation was a silicon-based inverse opal structure that traps light in the 1.5-micron bandgap range. “It was the first self-assembled photonic bandgap material on a length scale relevant to telecommunications,” says John.
The collaboration began when John approached Ozin. “I hadn’t heard of him,” says Ozin. “He started talking about photonic crystals, and I hadn’t heard of them either. He showed me incredible structures, and I thought, ‘My God, they are materials filled with holes.’ “ Ozin, who had “always worked with materials riddled with periodic arrays of holes,”...
