Organic Solar Cells Unaffected by Nanostructure
RALEIGH, N.C., Feb. 4, 2015 — Bulk heterojunction organic solar cells that are highly organized at the nanoscale are no more efficient at creating free electrons than cells with poorly organized structures. That is the finding of a research team led by North Carolina State...
3 Finalists Vie for National Integrated Photonics Institute
WASHINGTON, Feb. 3, 2015 — Three consortia led by the universities of Central Florida, Southern California and New York have been selected by the U.S. Department of Defense to submit full proposals for creating a $220 million Integrated Photonics Institute for Manufacturing...
Mobius Strips Conjured from Beam Polarization
ROCHESTER, N.Y., Jan. 30, 2015 — A light beam can be structured so that its polarization twists around like a Mobius strip. The finding, by a team of researchers from the U.S., Canada, and Europe, confirms a theoretical prediction that it is possible for light’s...
Ultrasonic Waves Create One-Way Optical Fiber
CHAMPAIGN, Ill., Jan. 30, 2015 — Ultrasonic waves can turn optical fiber into a one-way street for photons, a discovery that could aid the development of quantum computers. Researchers from the University of Illinois at Urbana-Champaign demonstrated the effect using a silica...
Digital Imaging Down, But Teledyne Ends the Year Up
THOUSAND OAKS, Calif., Jan. 29, 2015 — Despite lagging sales in its digital imaging department, Teledyne Technologies Inc. reported record profits as it closed the books on 2014. Total year sales were $2.4 billion, up 2.4 percent from $2.3 billion the previous year. Net income was $217.7...
Speed of Light Reduced in Free Space
EDINBURGH, Scotland, Jan. 29, 2015 — Passing a light beam through an optical mask can give its photons a transverse spatial structure that reduces their speed. Researchers from Heriot-Watt University and the University of Glasgow have reported delaying single photons by several microns...
Strong Fourth Quarter Keeps Jenoptik on Track
JENA, Germany, Jan. 29, 2015 — The Jenoptik Group said it is looking forward to a jump in revenues in the new year after ending 2014 with sales and earnings down slightly. The company’s preliminary numbers place earnings before interest and taxes (EBIT) at more than...
