PHOTONIC CRYSTAL PRIZE. "Light crystals clinch physics medal. US physicist Eli Yablonovitch, who first created "photonic crystals" to repel, trap and steer light, will receive the Newton Medal from the UK's Institute of Physics." Announced yesterday, and a harbinger of more to come. Worthy of a brief digression from piezoelectricity. https://lnkd.in/eTY9nZ7 View in LinkedIn

PROFESSOR YABLONOVITCH, a remarkable man with a stunning career. This award is just one of a string of honors for this truly innovative scientist who defied the skeptics and created 3D photonic crystals, exceeding what exists in nature. https://lnkd.in/es4HxUP View in LinkedIn

PHOTONIC CRYSTALS: SEMICONDUCTORS OF LIGHT. "Nanostructured materials containing ordered arrays of holes could lead to an optoelectronics revolution, doing for light what silicon did for electrons. The key was proving the skeptics wrong by showing that it was possible to create for light the same kind of phenomenon seen in electronic semiconductors—namely, a so-called band gap" or the forbidden zone. https://lnkd.in/eKrjXgP View in LinkedIn

BAND GAP SKEPTICS. "Many researchers greeted the idea of a photonic band gap with skepticism and disinterest when it was first proposed, but today photonic crystals are rapidly turning into big business. Photonic crystals have applications such as high-capacity optical fibers, color pigments and photonic integrated circuits that would manipulate light in addition to electric currents." https://lnkd.in/eKrjXgP View in LinkedIn

UNLIMITED POSSIBILITIES. "Unlike lattices of atoms, photonic crystals have structural possibilities limited only by the human imagination. Any shape can be sculpted at the lattice sites. Integrated circuits that combine conventional electronics and photonic crystals would represent" "the ultimate limit of optoelectronic miniaturization." http://optoelectronics.eecs.berkeley.edu/eliy_SCIAM.pdf View in LinkedIn

3D PHOTONIC CHIPS for computers could give a thousandfold increase in performance of computers. These crystals resemble the structure of diamond, with very broad photonic band gaps. https://lnkd.in/eMVH8KN View in LinkedIn

PHOTONIC PROPERTIES. "The crystal can thus form a kind of perfect optical “insulator,” which can confine light losslessly around sharp bends, in lower-index media, and within wavelength-scale cavities, among other novel possibilities for control of electromagnetic phenomena." http://ab-initio.mit.edu/photons/tutorial/photonic-intro.pdf View in LinkedIn

LIGHT TRUMPS ELECTRONS in information communication. This is an immense statement with many applications. Photonic crystals are like electrical insulators for light. And it all began with the seemingly frivolous, or at least innocent, fascination by scientists going back to Newton, for iridescent colors in nature. http://mpalffy.lci.kent.edu/Optics/Presentations%202012/Photonic%20Crystals%20Libo%20Weng.pdf View in LinkedIn

PIEZOELECTRIC TRANSDUCERS "convert small amounts of energy from one kind to another (for example, converting light, sound, or mechanical pressure into electrical signals)." http://www.explainthatstuff.com/piezoelectricity.html View in LinkedIn
