Photoacoustic techniques can supplement conventional imaging techniques in breast cancer diagnostics. From first tests on patients using the ¡¥photoacoustic mammoscope¡¦ developed by the University of Twente, researcher Dr. Srirang Manohar concludes that the images obtained add valuable information about the vascularisation of a tumor. The research has been done in cooperation with the Medisch Spectrum Twente hospital in Enschede, and the results are published in the online journal Optics Express.
Eblana Photonics Ltd. shipped the first batch of its single-wavelength laser diodes for analog and other ultra-narrow linewidth and low phase noise applications. The product series exhibits RIN down to -160 dB/Hz and emission linewidths below 100 kHz at emitted powers as low as 500 £gW.
A method for mass producing polymer opals that allow novel color-tuning characteristics has been developed by researchers in the UK and Germany. What's more, the researchers believe that they have found a way to make the materials more strongly colored which could open up a range of decorative, sensing, security and photonic applications.
Since Einstein, scientists have dreamed of Laser light powered rockets streaking through space at speeds approaching the speed of light. This vision came a step closer to reality on December 21, 2006, when Dr. Young Bae of the Bae Institute successfully demonstrated the world’s first Photonic Laser Thruster (PLT). Repeated experiments since then have reconfirmed results.
The universe's earliest stars may hold clues to the nature of dark matter, the mysterious stuff that makes up most of the universe's matter but doesn't interact with light, cosmologists report.
Electro-optics companies SCHOTT North America's Fiber Optics Defense Division in Southbridge, Mass., and Clear Align in Eagleville, Pa., are joining hands to design, prototype, and produce electro-optical solutions for defense and security applications.
Oncore Power Systems, of Newport Beach, CA, began producing a line of fiber-optic network cables and cable assemblies. The assemblies can be purchased in 10-Gbit laser-optimized or standard 50-µm multi-mode, 62.5/125 multi-mode, single-mode, and mode-conditioning cables.
Rural phone cooperative GVTC Communications has installed fiber-optic lines directly to buildings in the business district of Boerne, placing the small Hill Country town among a small percentage of U.S. cities outfitted with extensive fiber optics.
Researchers at the University of Illinois have discovered a way to generate light and reduce damage in a leading candidate for next-generation microelectronics lithography. The technique could help pack more power into smaller computer chips.
The conventional model for galaxy evolution predicts that small galaxies in the early Universe evolved into the massive galaxies of today by coalescing. Nine Lego-like “building block” galaxies initially dete...
