The article features the importance of hollow-core photonic-crystal fiber (HC-PCF) guide in the U.S. It reveals that nonlinear and quantum optics cannot transport tightly focus laser beams over long distances without the constraints of diffraction but with the development of HC-PCF such wish is realized because the technology has the ability to confine gases and light together at mode areas of several square microns while maintaining its interaction over lengths exceeding several hundred meters.

The article discusses analytical spectroscopy and telecommunication photonics. telecommunications optical channel monitor (OCM) is a highly specialized and optimized spectrometer that produces a chart of power versus wavelength. All optical components for an OCM are contained in a single 14-pin butterfly package. Traditional laboratory and process spectrometers used for analytical chemistry rely on tungsten-halogen light bulbs as their broadband source. Semiconductor light sources are commercially available from several vendors in the traditional telecommunications region of the spectrum.

The article reports on meeting on nanophotonics at Stanford Photonics Research Center in Palo Alto, California. As usual, topics covered in the three-day multidisciplinary optics meeting ranged from the farthest reaches of fundamental optical sciences, such as quantum computing with linear optics, to everyday commercial realities, such as the technical challenges of meeting explosive consumer demand for cameras in cell phones. So nanophotonics, a field in which fundamental enabling research continues at the same time as companies and products are beginning to appear on the market, seemed an apt topic choice for the annual industry panel session.

The article discusses the concept of silicon photonics. With this, the authors cites images which soon be replaced by a web-like network of silicon islands surrounded by fine silicon wires. Researchers at Stanford University in California can create flexible silicon arrays 50 times larger than the original silicon chips. In this context, a scanning-electron micrograph is presented which shows a silicon island surrounded by coiled silicon wires.

The article highlights the conference on Executive Panel: Market Direction and Implications for the World of Photonics in Bridgewater, New Jersey. According to Giorgio Anania, president and CEO of Bookham Inc., photonics companies must look beyond the communications industry to industries with healthy market size and longevity. It offers information about the availability of a working model of an illumination-delivery system.

The article presents information about the adaptive scanning optical microscope (ASOM). An ASOM with a six element objective lens can have up to a two-order-of-magnitude larger overall field size than a conventional microscope with a six-element objective. The objective lens of an ASOM has a curved field scanned by a mirror placed at its center of curvature. The microscope images two objects fixed in space and a microgripper that travels between them.

Reports on the development of a linear Bragg-Fresnel lens places on an initially flat multilayer substrate, in which the lens focuses in on axis while the substrate, when bent, focuses in the other. Application in optics that focus hard x-rays; Contact information.

Reports on the findings of Shizuoka University researchers that the incorporation of a birefringent lens into a multielement lens design can reduce the effect of off-axis aberrations to a practical degree. Occurrence of the effect in single-element birefringent lenses; Calculation of the effects of spherical aberration.
