Electro-Optic Polymers Improve Speed and Power Efficiency
Jun 26, 2020 — The search is on for new building blocks to increase the speed of optoelectronic components and decrease electrical power consumption. High-performance electro-optic (EO) materials have matured commercially and have the potential to offer solutions....
High-Performance Vector Polarizer Tailors Light
NANJING and TIANJIN, China and ORLANDO, Fla., Dec. 18, 2017 — A newly proposed design for a vector polarizer could enable flexible filtering of a wide range of light sources and the generation of new light states. The design can be used to tailor light intensity, phase and polarization. To increase polarizer...
Highly Efficient Beamsplitter for THz Uses Artificial Dielectrics
PROVIDENCE, R.I., July 24, 2017 — A novel technique for manipulating the polarization of light at terahertz (THz) frequencies uses stacks of closely-spaced steel plates to make a polarizing beamsplitter (PBS). Each pair of plates forms a parallel-plate waveguide. When THz light is...
Photodielectric Discovery Could Mean Greater Optical Control for Electronics
NAGOYA, Japan, May 15, 2017 — The instrinsic photo-dielectric effect (PDE), which uses light to increase the permittivity of the dielectric used in capacitors, could aid in the development of photo-capacitors that would enable the remote control of the dielectric response via...
A*STAR Institute, Picosun to Develop ALD
Jun 1, 2012 — A*STAR Institute of Microelectronics (IME) of Singapore and Picosun Oy, an Espoo, Finland-based global manufacturer of atomic layer deposition (ALD) equipment, have partnered to develop advanced ALD techniques to enable continued growth in...
A*STAR Institute, Picosun Team to Develop ALD
ESPOO, Finland, and SINGAPORE, March 28, 2012 — The two organizations have partnered to develop advanced atomic layer deposition techniques to enable continued growth in next-generation memories and solar cells.
Lasers Change the Shape of the Photovoltaics Industry
Mar 1, 2012 — Laser technology and photovoltaics manufacturing make naturally happy partners. Lasers lend themselves well to the needs of PV development such as drilling, trenching, ablation, welding and doping. Lasers may have been made for photovoltaics...
Organic electronics printed on CDs, DVDs
LOS ANGELES – A new patterning technique uses commercially available technology to print conducting polymers using an infrared laser onto standard CDs and DVDs, a feat that could propel current proof-of-concept organic devices – organic LEDs, thin-film...
Plasmonic resonances found in quantum dots
BERKELEY, Calif. – Until recently, plasmonic properties have been limited to nanostructures with interfaces between noble metals and dielectrics. But now researchers have discovered that plasmonic properties also can be achieved in quantum dots. Scientists at the...
Plasmonic Resonances Found in QDs
BERKELEY, Calif., April 25, 2011 — Until now plasmonic properties have been limited to nanostructures that feature interfaces between noble metals and dielectrics. Now researchers have discovered that plasmonic properties can also be achieved in quantum dots. "We have...
Transformation Optics Makes a U-turn
BERKELEY, Calif., July 7, 2010 — In transformation optics, light waves can be controlled at all lengths of scale through the unique structuring of metamaterials, composites typically made from metals and dielectrics — insulators that become polarized in the presence of an...
Nanoscale Physical Phenomenon Discovered
ANN ARBOR, Mich., May 24, 2010 — A nanoscale phenomenon has been discovered that could lead to faster, less expensive portable diagnostic devices and push back frontiers in building micro-mechanical and "lab on a chip" devices. In our macroscale world, materials called conductors...
Merck to Present Green Materials at SID
DARMSTADT, Germany, May 20, 2010 — For SID Display Week in Seattle (May 23 to 28), Merck KGaA is using the heading green³ to convey how environmentally friendly its materials are. Specifically, green³ stands for producing eco-friendly materials, enabling eco-friendly...
SmartKem Appoints Griffiths as Senior Scientist
ST. ASAPH, North Wales, April 12, 2010 — The developer of novel materials and processes that create high-resolution microelectronic components directly onto thin flexible printed electronics, SmartKem Ltd. announced it has appointed Russell Griffiths to the position of senior scientist. In...
Patterned Metal Films Focus Surface Plasmon Polaritons
Oct 1, 2005 — A team of investigators at the University of California, Berkeley, has demonstrated that circles and ellipses milled in silver films can focus surface plasmon polaritons. The development may enable the creation of ultrasmall integrated...
Daily News Briefs
Aug 24, 2005 — Daktronics Inc., a South Dakota-based maker of display systems for sports, business and transportation applications, was chosen by Indiana University (IU) to design, build and install an integrated scoring and video display system at Branch...
The Pros and Cons of Protected and Surface Coatings for High-Phase-Thickness Applications
Jul 1, 2005 — Metal salt compounds, or dielectrics, produce thin-film coatings with precise spectral control. Because they are soft and require glass coverslips laminated to the coating substrate to protect them from damage, they are called protected coatings....
Ultrafast Lasers Enable All-Optical Histology
Aug 1, 2003 — Following work by other researchers with dielectrics, metals and various biological tissues, scientists from the University of California, San Diego, Colorado School of Mines in Golden, and Science Applications International Corp. of Arlington and...
