:: Discovery Channel uses Photron cameras to capture high-speed events
Discovery Channel's new series Time Warp uses new technologies to bring never-before-seen wonders into a visual form that your body can actually process, with the help of Massachusetts Institute of Technology (MIT) scientist and teacher Jeff Lieberman, along with digital-imaging expert Matt Kearney of Tech Imaging Services. In one example, a Photron (San Diego, CA) high-speed camera captures a whip blowing out a candle and the shock wave that follows.

:: Koheras invests in Arctic; enters strategic agreement on lasers
Koheras (Birkerod, Denmark), part of the NKT Photonics and manufacturer of SuperK white-light fiber lasers and systems, together with Arctic Photonics (Jorvas, Finland), a manufacturer of pulsed solid -state laser products, announced the signing of a strategic collaboration agreement in which Koheras will gain access to Arctic's ultracompact, short-pulse solid-state laser technology and its laser design competence.

:: Novaled AG secures 8.5 million Euros in equity financing
Novaled AG (Dresden, Germany), a producer of organic light-emitting diodes (OLEDs) for lighting and display products, closed its third round of financing with a volume of 8,5 million Euros, which were exclusively provided by existing shareholders of the company. Participants in this round were eCAPITAL, TechnoStart, KfW and TUDAG, all from Germany, as well as Credit Agricole Private Equity, TechFund and CDC Innovation, all from France.

:: Energetiq Technology secures Series C funding for short-wavelength light sources
Energetiq Technology (Woburn, MA), developer and manufacturer of specialized short-wavelength light products for applications in biooptics and semiconductor manufacturing applications, raised additional capital in its Series C round of financing. The financing was led by a new investor, Ushio (Tokyo, Japan), and supported by existing investors including Intel Capital and Shea Ventures.

TECHNOLOGY NEWS

:: University of Florida scientists achieve record efficiency for blue OLEDs
University of Florida (UF; Gainesville, FL) scientists achieved a new record in efficiency for blue organic light-emitting diodes (OLEDs). Because blue is essential to white light and necessary to produce lighting that is more efficient than compact fluorescents yet similar to standard incandescent bulbs, "The quality of the light is really the advantage," said Franky So, a UF associate professor of materials science and engineering and lead investigator on the project.

:: NIST researchers develop nanoindentation technique to measure thin-film toughness
Researchers at the National Institute of Standards and Technology (NIST) have developed a method to measure the toughness--the resistance to fracture--of the thin insulating films that play a critical role in high-performance integrated circuits. The new technique could help improve the reliability and manufacturability of ICs and, better yet, microelectronics manufacturers can perform the test using equipment they already own.

:: Noninvasive strain mapping approach boasts nanoscale spatial resolution, no sample prep
Researchers at CIC nanoGUNE (San Sebastian, Spain) and the Max Planck Institutes of Biochemistry and Plasma Physics (Munich, Germany) say they have accomplished non-invasive, nanoscale-resolved infrared mapping of strain fields in semiconductors. Their approach, based on near-field microscopy, is described in Nature Nanotechnology. It promises to enable new ways of analyzing mechanical properties of high-performance materials, and contact-free mapping of local conductivity in strain-engineered electronic devices.

:: "Industry first" distributed PMD analyzer pinpoints optical network problems, simulates repair effect
EXFO Electro-Optical Engineering Inc. (Quebec City, Canada) says it has achieved a breakthrough for characterizing polarization mode dispersion (PMD) in high-speed optical networks with the launch of its new FTB-5600 Distributed PMD Analyzer. This field-ready, single-ended test system promises network operators a far deeper understanding of their system performance when looking to upgrade a fiber optic network to 10, 40 or even 100 Gbit/s.

Siskiyou top-adjust stages boast 2mm travel and top-locking in a very small footprint.
The unique angled drive provides 170 pitch resolution from the 100 pitch drive screw (pat. Pend.).
The “torque reduction bearing” minimizes rotational torque to the moving platen for superior
flatness of travel(pat. Pend.). Two sizes of single axis stackable versions available.

NEW PRODUCTS

:: Raman spectrometer
A 1064 nm Raman spectrometer is designed for the biomedical market. The wavelength reduces biofluorescence while the Raman signal remains high. The system uses a fiber laser with up to 400 mW of output power, with built-in bandpass and blocking filters. The f/2, volume-phase transmission grating is designed to capture five times more light than reflective grating spectrographs.

:: Pulse shaping and measurement
The DazScope is an 800 nm pulse-optimization sytem used in CPA lasers to automatically minimize and stabilize the amplified pulse duration. The Phazzler is a full-pulse measurement system, with autocorrelation, FROG, XFROG, and single-shot SPIDER measurements. Both are based on the Dazzler inline acousto-optic programmable dispersive filter.

:: Beam-delivery mirrors
The B-Max series mirrors support Ti:sapphire systems with pulse widths of 10 fs or less, providing better than 99.8% reflectivity from 735 to 880 nm. The E-Max high reflectors operate over the 770 to 840 nm range for systems where high pulse energy damage threshold is a primary concern. Both thin-film coatings minimize group velocity and third-order dispersion.

FOCUS ON: NANOPHOTONICS

:: Direct-write nanopatterning uses optically trapped microspheres
In an extension of nanopatterning methods that use self-assembled microspheres (see www.laserfocusworld.com/articles/325407), researchers at Princeton University (Princeton, NJ) are able to perform subwavelength direct-write nanopatterning using an optically trapped microsphere.

:: FOL Symposium reveals what’s next in photonics
Held on December 4 and 5, 2008, the Boston University (BU) Photonics Center’s annual Future of Light (FOL) Symposium was the 12th in the series and concentrated on the topics of nanophotonics and plasmonics. About 200 guests attended the event, filling it virtually to capacity.

:: Near-field polishing yields ultraflat silica surface
While CMP methods can yield surface roughnesses on fused silica down to approximately 2.36 Å, scientists at the Japan Science and Technology Agency (SORST), the University of Tokyo, and Sigma Koki (all in Tokyo, Japan) have developed an optical near-field, nonadiabatic photochemical photodissociation process that can further polish this type of surface to a roughness of only 1.37 Å.
