More than 70 astronomers gathered on Capitol Hill this week, not to talk about the demise of a major national research facility, but to plan for its scientific future. With optimism, the group was planning the next 15 years of research for Puerto Rico's Arecibo Observatory, the home of the world's largest radio telescope.
Eblana Photonics Ltd. has announced first shipments of single wavelength laser diodes for analog and other applications that demand ultra-narrow linewidth and low phase noise operation. This latest product series extends and complements Eblana's existing family of cutting edge laser products which target high volume applications such as GPON, 10GBASE-LR/LRM/LW and 10.0G Fibre Channel.
Axsun Technologies Inc., a leading developer and manufacturer of advanced photonic components and subsystems, today announced further expansion of their industry-leading OMx(TM) optical monitor product family with the introduction of the Channel Power Monitor (CPM), Optical Power and Wavelength Monitor. Introduced for the first time at the European Conference on Optical Communication (ECOC) in Berlin, Germany, Axsun's new optical monitor product delivers the right balance of performance, scalability and economics needed for cost-conscious metro applications.
Three adaptive optics technologies available from Imagine Optic have been packaged together into a kit targeted at bioimaging applications.
Mirrors have special powers in the real world too, especially in the hands of an astronomer. In fact, modern astronomy depends on mirrors. Almost every telescope uses a mirror, sometimes several mirrors, to gather and guide starlight toward some super-sensitive digital detector where a breathtaking image can be formed. Without mirrors, it would be almost impossible to study the universe.
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.
