FEDs to Come to Market

FEDs to Come to Market Back in the mid-1990s, field-emission displays (FEDs) were hot. After all, what was not to like: an array of tiny cathode ray emitters that formed a low-power, bright flat panel display with no viewing-angle dependency, no need for backlighting, power conditioning, or sophisticated encapsulation. Unfortunately, the technology was plagued by fabrication and yield issues and overtaken by LCDs and organic, light-emitting diode (OLED) displays. Now, Sony-spinout Field Emission Technologies Inc. has announced plans to put a 26 in. FED panel into volume production by the end of 2009. Could it be the harbinger of yet another sea change in an already surging displays market?

Lasers Narrow Scope

Lasers Narrow Scope Using surface plasmons, a group of researchers has reduced the beam divergence of an edge-emitting diode laser operating at 9.9 μm by a factor of 25. The group added a grating and subwavelength slit to the laser's facet to achieve divergence angles as small as 2.4 degrees. Applications include communications, laser ranging, and metrology.

Substrate Cuts LED Costs

Substrate Cuts LED Costs By substituting metal-coated silicon for the sapphire-coated substrates used to make white light LEDs, researchers have found a way to reduce the cost of the devices, making them more practical for general lighting applications. The group epitaxially grew gallium nitride on a multilayer stack of (111) zirconium nitride (ZrN) and (0001) aluminum nitride (AlN) applied to a silicon substrate. The ZrN acted as back reflector and ohmic contact, and the AlN provided electrical isolation while conducting away heat and acting as a reaction barrier.

Nanoholes Offer High Resolution Imaging

Nanoholes Offer High Resolution Imaging In a device that sounds sort of like a high-tech pinhole camera, a group of UK researchers have developed a nanohole array that can image to resolutions as good as 200 nm. Fabricated in a metal screen, the quasi-crystal array functions as a lens to image both coherent and incoherent point sources. Although the method cannot currently be used for practical imaging applications, it appears that an appropriately patterned array could image an extended source.

Confined Light Goes Far

Confined Light Goes Far A hybrid optical waveguide can confine light to around 10 nm, offering the prospect of improved optical communications. Formed by a silver nanowire placed nanometers away from a silver substrate, the waveguide strongly confines surface plasmon polaritons, allowing them to propagate for 40 to 150 μm. Applications include optical computing.

Tiny Pictures

Tiny Pictures A hybrid X-ray microscope combines coherent diffractive imaging with scanning transmission X-ray microscopy to yield super-high-resolution micrographs. The system incorporates a megapixel Pilatus detector to produce raster-scanned X-ray diffraction data that is processed to produce images. Meanwhile, a group at Lawrence Berkeley Laboratory has used a free-electron laser to produce nanoscale images with Fourier transform holography.

Eat Your Sensors

Eat Your Sensors We've all heard about the detectors that can be swallowed to provide images as they pass through the body. Now, Tufts University researchers have used silkworm fiber to develop optics that can be used for biocompatible, edible sensors that biodegrade. The group extracted sericin protein from the silk fiber and molded it into gratings and microlens arrays, controlling surface morphologies to 125 nm.

Quantum Cryptography Poised for Mainstream

Quantum Cryptography Poised for Mainstream By converting photons to random sequences of numbers, a new cryptography chip provides quantum keys to both parties in a secure link. With quantum theory, any attempt to observe the photons will change their state, making any attempts at eavesdropping obvious. If the chip meets its promised volume production schedule of 2010, it would be the first commercial quantum cryptography product.

Curved Detector Sees Clearly

Curved Detector Sees Clearly By integrating single-crystalline silicon detectors and electronics into a stretchable mesh, researchers have developed a conformal imager that could possibly be developed into an artificial retina. The group first molded a hemispherical rubber membrane. They next stretched it flat to apply a focal plane array that incorporated 2D compressible configurations and elastomeric transfer elements. When the membrane was released and returned to its hemispherical shape, the optoelectronics conformed to it.
