Gel Filters Various Wavelengths of Light as its Temperature Changes
GAITHERSBURG, Md., July 18, 2022 — A colloidal gel developed at the National Institute of Standards and Technology (NIST) has demonstrated that it can control structural color and light transmission. Called SeedGel by its creators, the material was originally developed for industrial and bioengineering use. The researchers have now found a new use for the gel as a temperature-sensitive light filter. According to researcher Yun Liu, a scientist at the NIST Center for Neutron Research (NCNR) and a professor at the University
Selective Light Transmission Could Advance Optical Computing
CHAPEL HILL, N.C., July 19, 2018 — A new way to select and send light of a specific color over long distances has been applied to development of a nanoscale “light switch” for turning on and turning off the transmission of one color of light. The technique, which uses...
Screen Saver
Dec 12, 2014 — Let’s face it: We spend a large portion of our day looking at screens. The jury is still out on whether that’s an entirely good or bad thing, but it is the reality of modern life. Our ever-evolving arsenal comprises cellphones, tablets,...
Touch Screens Repel Fluids, Cut Glare and Still Look Good
BARCELONA, Spain, July 17, 2014 — Touch screens with nanostructured surfaces that ward off glare, reflection and fluids could easily be mass-produced, according to researchers from the Institute of Photonic Sciences. In one study, the researchers demonstrated a highly transparent...
THz Plasmonic Crystal is Tunable
ALBUQUERQUE, N.M., Oct. 30, 2013 — Normally the light passing through the atomic structure of a photonic crystal is of a fixed frequency, but light passing through a crystal containing plasma can be tuned by adjusting the voltage applied to it, say researchers in New Mexico. Photonic...
Optical fiber design uses Anderson localization
MILWAUKEE – The first practical application of “Anderson localization” – a Nobel Prize-winning phenomenon proposed in 1958 – has yielded a new method for transmitting light through optical fibers. Data transmission through conventional...
Optical Fiber Design Uses Anderson Localization
MILWAUKEE, April 18, 2013 — The first practical application of “Anderson localization” — a Nobel Prize-winning phenomenon proposed in 1958 — has yielded a new method for transmitting light through optical fibers.
IBM, Dow Corning Team to Develop Board-Level Photonics Materials
SAN FRANCISCO, Feb. 7, 2013 — IBM and Dow Corning have developed a new type of polymer material capable of transmitting light instead of electrical signals at high speed within supercomputers and other data systems.
Nanohole-Based Sensors Ideal for Medical Diagnostics
SINGAPORE, July 20, 2012 — Novel molecular sensors based on thin metallic films with nanoholes hold promise for medical diagnostic applications where it is necessary to detect small quantities of molecules.
3M Completes Expansion of Solar Film Plant
ST. PAUL, Minn., June 19, 2012 — The company completed manufacturing expansion for its 3M Ultra Barrier Solar Film in Columbia, Mo., a move that supports the increased demand for high-efficiency flexible photovoltaic modules.
Blocked holes boost light on the nanoscale
PRINCETON, N.J. – Capping a hole should block light transmission through that hole, right? Not on the nanoscale. In fact, placing a metal cap over a small hole in a metal film does not stop light from passing through the hole, but rather enhances its transmission....
Blocked Holes Enhance Light Transmission
PRINCETON, N.J., Nov. 28, 2011 — Placing a metal cap over a small hole in a metal film does not stop light from passing through the hole, but rather enhances its transmission — quite contrary to the conventional thought that blocking a hole would allow less light to pass...
PG&O Appointed West Coast Distributor for Schott Supremax
SANTA ANA, Calif., Nov. 7, 2011 — Precision Glass & Optics (PG&O) has announced an exclusive West Coast distributorship agreement with specialty glass provider Schott North America Inc. for its new Supremax 33 rolled sheet borosilicate glass. With an identical...
Carbon nanotubes as optical antennae
ITHACA, N.Y. – Researchers at Cornell University have found that carbon nanotubes’ light transmission behaves as a scaled-down version of radio-frequency antennae found in walkie-talkies, except that the interaction is with light instead of radio waves. The...
Bayer Makes Flame-retardant Polycarbonate for LEDs
PITTSBURGH, Sept. 20, 2010 — Bayer MaterialScience LLC has developed a flame-retardant polycarbonate plastic that enables LED and other electronics manufacturers to slim down lenses and covers. Makrolon FR7067 polycarbonate plastic meets the UL-94 V0 rating at 1.5 mm,...
