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." Nature has been experimenting with these natural semiconductors for millions of years, and the parade of iridescent coloration in nature is also the roadmap for future industries. https://lnkd.in/eKrjXgP View in LinkedIn

NATURE HOLDS THE PATENTS. "All the magic of semiconductors—the switching and logic functions—comes about from controlling the availability of electrons and holes above and below the band gap." https://lnkd.in/eKrjXgP View in LinkedIn

PHOTONIC BUSINESS. "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." http://optoelectronics.eecs.berkeley.edu/eliy_SCIAM.pdf View in LinkedIn

SEMICONDUCTORS OF LIGHT = PHOTONIC CRYSTALS. "Nanostructured materials containing ordered arrays of holes could lead to an optoelectronics revolution, doing for light what silicon did for electrons. The microelectronics and information revolution is based on the elaborate control of electric currents achieved with semiconductors such as silicon. That control depends on a phenomenon called the band gap: a range of energies in which electrons are blocked from traveling through the semiconductor." https://lnkd.in/eKrjXgP View in LinkedIn

PHOTONIC GUANINE NANOCRYSTALS also serve the chameleon in thermal protection. The same is true for certain algae. https://lnkd.in/e3hJaJj View in LinkedIn

TUNABLE PHOTONIC CRYSTALS are at the heart of chameleon color changes. This is a reminder of how little we understand the coloration of these animals. The proximity of the guanine nanocrystals changes according to the excitation of the animal, causing color shifts. How they change the spacing in these crystal lattices remains illusive. https://lnkd.in/eVmgREB View in LinkedIn

NEW EPIPHANY. "You can program everything from bits, to atoms, and even large-scale structures." https://lnkd.in/e74uquz View in LinkedIn

PHOTONIC CRYSTALS cause chameleon color changes. "Chameleons shift colour through active tuning of a lattice of guanine nanocrystals...and a deeper population of iridophores with larger crystals reflect a substantial portion of sunlight." https://lnkd.in/eEphswK View in LinkedIn

EMBEDDED INFORMATION. "In the information age, it seems inevitable that we’re eventually going to start building information, and computation, into the building blocks of matter itself." https://lnkd.in/dzmMmjE View in LinkedIn
