Eli Yablonovitch (born 15 December 1946) is an American physicist and engineer who, along with Sajeev John, founded the field of photonic crystals in 1987. He and his team were the first to create a 3-dimensional structure that exhibited a full photonic bandgap, which has been named Yablonovite. In addition to pioneering photonic crystals, he was the first to recognize that a strained quantum-well laser has a significantly reduced threshold current compared to its unstrained counterpart. This is now employed in the majority of semiconductor lasers fabricated throughout the world. His seminal paper reporting inhibited spontaneous emission in photonic crystals is among the most highly cited papers in physics and engineering.

Career

Yablonovitch received his B.Sc. in physics from McGill University in 1967. He went on to receive his A.M. degree in applied physics from Harvard University in 1969, and his Ph.D. from Harvard in 1972. During his post-graduate studies, Yablonovitch worked on nonlinear optics with carbon dioxide lasers.

After receiving his Ph.D., Yablonovitch worked at Bell Laboratories. He then became a professor of applied physics at Harvard in 1974. In 1979, he joined Exxon research center to work on photovoltaic research for solar energy.

Yablonovitch co-founded Luminescent Inc. in 2002. Luminescent provided sophisticated mathematical optimization for use in photolithography masks. Luminescent was acquired by Synopsys in 2012.

Fellowships and awards

He is a Fellow of the Institute of Electrical and Electronics Engineers (IEEE), the Optical Society of America (OSA), and the American Physical Society (APS).

He was elected a member of the National Academy of Sciences, the National Academy of Engineering, the National Academy of Inventors, the American Academy of Arts and Sciences, and a Foreign Member of the Royal Society of London.

He is a recipient of the:

  • 1978 Adolph Lomb Medal;
  • 1993 W. Streifer Scientific Achievement Award;
  • 1996 R. W. Wood Prize;
  • 2001 Julius Springer Prize;
