Nanowire Transistors Realized
WEST LAFAYETTE, Ind., Nov. 30, 2009 – A new generation of ultrasmall transistors and more powerful computer chips using semiconducting nanowires are closer to reality after researchers at IBM, Purdue and UCLA learned how to make them with layers of materials that are sharply defined at the atomic level, a critical requirement for making efficient transistors.
QDs Improve Medical Imaging
GAITHERSBURG, Md., Nov. 19, 2009 – Changes in a living cell that take place over a long period of time are difficult to scrutinize and require high-spatial-resolution imaging. But new research now makes it possible to analyze activities that occur over hours or even days inside...
Show Plans Laser Tribute
SAN FRANCISCO, Nov. 6, 2009 – Special events celebrating the 50th anniversary of the invention of the laser, including a "Cirque du Lasaire" reception, will mark SPIE Photonics West’s first year in San Francisco. The primary photonics technical symposium and exhibition in...

SAN FRANCISCO, Nov. 6, 2009 – Special events celebrating the 50th anniversary of the invention of the laser, including a “Cirque du Lasaire” reception, will mark SPIE Photonics West’s first year in San Francisco. The primary photonics technical symposium and exhibition in North...
Atom Imaged in Ultracold Gas
CAMBRIDGE, Mass., Nov. 5, 2009 – A high-resolution microscope was developed to image individual atoms in an ultracold quantum gas, marking the first time scientists detected single atoms in a crystalline structure made solely of light called a Bose Hubbard optical lattice.
CDI Awarded Nanotech Patent
Nov 4, 2009 — Carbon Design Innovations Inc. (CDI) of Burlingame, Calif., has announced that it has received a key technology patent for the fabrication of carbon nanotube devices. US Patent No. 7,601,650 was issued Oct. 13, 2009, for a variety of methods and...
Scope-Headed Rats Roam Free
TÜBINGEN, Germany, Nov. 4, 2009 – By building a tiny laser microscope small enough to mount on a rat’s head, researchers found a way to solve the puzzle of recording meaningful signals from brain cells that calculate perception and attention while the subject is in motion.
Frequency Comb Shows Teeth
GAITHERSBURG, Md., & KONSTANZ, Germany, Nov. 2, 2009 – The first optical frequency comb that actually looks like a comb has been built and demonstrated by scientists in the US and Germany. The "teeth" of the new comb – a tool for precisely measuring different frequencies of visible light – are separated...
Dimple lens goes beyond the diffraction limit
LOS ANGELES – University of California scientists have created a new type of lens that can focus light down to a sub-100-nm spot. This record-breaking focusing power could open up new areas of research in biological sciences, nonlinear optics and near-field...
Microscope Distributor
Nov 1, 2009 — To extend its reach and promote its products in the former Soviet Union, Asylum Research of Santa Barbara, Calif., has signed a distribution agreement with Intertech Corp. of Atkinson, N.H. The latter company will sell and support its partner’s line...
The microscopy market: Delivering to the desktop
WELLESLEY, Mass. – Worth about $2.4 billion in 2008, the global market for microscopes and accessories is projected to fall to $2.1 billion in 2009, then to rise to $3.6 billion in 2014 with a compound annual growth rate of 11.5 percent, according to a report from...
Linear Nanowires Kinked
CAMBRIDGE, Mass., Oct. 22, 2009 – Taking nanomaterials to a new level of structural complexity, Harvard University scientists determined how to introduce kinks into arrow-straight nanowires, transforming them into zigzagging 2- and 3-D structures with correspondingly advanced...
Molecules Made Mini Lasers
CAMBRIDGE, Mass., Oct. 21, 2009 -- A new optical microscopy technique squeezes photons out of nonfluorescent molecules to provide 3-D images of living cells and tissues for applications in medical imaging and biological research.
Byer to Chair Mobius Board
Oct 20, 2009 — Mobius Photonics of Santa Clara, Calif., a producer of short pulsed fiber laser sources, has named company co-founder Robert L. Byer chairman of its board of directors. Byer is the 2009 winner of the Frederic Ives Medal, the highest award given by...
FiO: Notes from the Crucible
SAN JOSE, Calif., Oct. 15, 2009 – “Whoa, whoa, whoa,” I thought. “Whoa.” I had just stumbled across a page on the Frontiers in Optics Web site collecting blog postings about the (then) upcoming meeting. “We can’t have people just running around writing stuff for the Internet. About...

Nanostrings Serve as Probes
GARCHING, Germany, Oct. 14, 2009 – New fabrication techniques have enabled the development of on-chip mechanical elements with dimensions on the nanometer scale. Their application, however, has been limited by the lack of sufficiently sensitive techniques for measuring the motion of...
Machine Mimics Human Vision
CHESTNUT HILL, Mass. Oct. 8, 2009 – Human vision is designed to look at the rough outlines of the various objects before examining the details. This improves the speed and accuracy of our image recognition, while machine vision typically performs the task in the opposite manner.
Seeing Inside a Living Cell
CAMBRIDGE, Mass., Oct. 8, 2009 – Electron microscopes are the most powerful type of microscope, capable of distinguishing even individual atoms. However, these microscopes cannot be used to image living cells because the electrons destroy the samples. Now, MIT assistant...
Catching photons in a bottle
MAINZ, Germany – Physicists at Johannes Gutenberg University have developed a bottle-shaped, monolithic microresonator that captures light and tunes it to arbitrary optical frequencies. To do this, they stretched a glass fiber until it reached about half the...
Asylum Orders Surge 60% in Q3
SANTA BARBARA, Calif., Oct. 2, 2009 -- Atomic force and scanning probe microscope maker Asylum Research said its orders for the third quarter are up more than 60 percent, driven largely by the introduction of a new high-resolution AFM, the popularity of two MFP-3D™ AFMs and the...
Mobius Laser Used at Max Planck
Oct 2, 2009 — Santa Clara, Calif.-based Mobius Photonics, producer of short pulsed fiber laser sources (IR, green, and UV), announced that its G1+ laser system has been used in stimulated emission depletion (STED) microscopy experiments at the Max Planck...
A closer look at plastic solar cells
Oct 1, 2009 — Plastic solar cells are lightweight, flexible and, most importantly, cheap to make. But so far, these devices lack one thing: efficiency. Now researchers at the University of Washington in Seattle believe that they may have the key to unlocking...
