Eli Yablonovitch
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.M.Kapoor (2013Electromagnetic Band Gap Structures page 58 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. Education 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Isaac Newton Medal
The Isaac Newton Medal and Prize is a gold medal awarded annually by the Institute of Physics (IOP) accompanied by a prize of £1,000. The award is given to a physicist, regardless of subject area, background or nationality, for outstanding contributions to physics. The award winner is invited to give a lecture at the Institute. It is named in honour of Sir Isaac Newton. The first medal was awarded in 2008 to Anton Zeilinger, having been announced in 2007. It gained national recognition in the UK in 2013 when it was awarded for technology that could lead to an 'invisibility cloak'. By 2018 it was recognised internationally as the highest honour from the IOP. Recipients * 2021 - David Deutsch for "founding the discipline named quantum computation and establishing quantum computation's fundamental idea, now known as the ‘qubit’ or quantum bit." * 2020 - Nader Engheta for "groundbreaking innovation and transformative contributions to electromagnetic complex materials and na ...

Yablonovite
Yablonovite is a photonic crystal structure that has an inverse cylindrical holes arranged in a diamond lattice. It was the first 3D photonic crystal to be fabricated with a complete photonic bandgap. It was created in 1991 by Eli Yablonovitch and his team.Yablonovitch, El"Photonic Crystals: Semiconductors of Light" ''Scientific American'', December 2001, accessed February 22, 2011. The structure that Yablonovitch was able to produce involved drilling a triangular array of cylindrical holes in layers of transparent material, where the holes of each layer are placed on top of the remaining material in the layer below, the structure repeats every 4 layers, and was modeled after an inverse diamond structure.

Photonic Bandgap
A photonic crystal is an optical nanostructure in which the refractive index changes periodically. This affects the propagation of light in the same way that the structure of natural crystals gives rise to X-ray diffraction and that the atomic lattices (crystal structure) of semiconductors affect their conductivity of electrons. Photonic crystals occur in nature in the form of structural coloration and animal reflectors, and, as artificially produced, promise to be useful in a range of applications. Photonic crystals can be fabricated for one, two, or three dimensions. One-dimensional photonic crystals can be made of thin film layers deposited on each other. Two-dimensional ones can be made by photolithography, or by drilling holes in a suitable substrate. Fabrication methods for three-dimensional ones include drilling under different angles, stacking multiple 2-D layers on top of each other, direct laser writing, or, for example, instigating self-assembly of spheres in a matri ...

Sajeev John
Sajeev John, OC, FRSC (born 1957) is a Professor of Physics at the University of Toronto and Canada Research Chair holder. 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 1984–1986 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 1985-1989. From 1986-1989 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 ...

Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as applie ...

Harvey Prize
Harvey Prize is an annual Israeli award for breakthroughs in science and technology, as well as contributions to peace in the Middle East granted by the Technion in Haifa.
