NeoPhotonics today announced the release of fully athermal and fully passive Arrayed Waveguide Grating (AWG) MUX/DMUX modules with a 50 GHz channel spacing. These devices have up to 44 channels and incorporate the same, patented stabilization and Photonic Integration Circuit (PIC) technology as the company’s extensive line of 100GHz channel spacing athermal AWGs, which have been shipping in volume to customers around the world since 2004.
OmniVision Technologies, Inc., the world's largest supplier of CMOS image sensors, today claimed a mobile handset industry first with the introduction of the OV3642, a 1/4-inch, 3 megapixel CameraChip(TM) sensor with TrueFocus(TM) technology embedded on-chip.
Taking advantage of the presence of light echoes, a team of astronomers have used an ESO telescope to measure, at the 1% precision level, the distance of a Cepheid - a class of variable stars that constitutes one of the first steps in the cosmic distance ladder.
Scientists hope that a new supercomputer being built by Syracuse University's Department of Physics may help them identify the sound of a celestial black hole.
ESA's test centre is buzzing with activity and anticipation as it welcomes its latest guest. The gigantic telescope of ESA's space-based infrared observatory, Herschel, is being prepared to be assembled with its spacecraft in the next few weeks.
NASA's Deep Impact spacecraft is aiming its largest telescope at five stars in a search for alien (exosolar) planets as it enters its extended mission, called EPOXI. Deep Impact made history when the mission team directed an impactor from the spacecraft into comet Tempel 1 on July 4, 2005. NASA recently extended the mission, redirecting the spacecraft for a flyby of comet Hartley 2 on Oct. 11, 2010.
Alps Electric today announces the launch of new aspherical glass lenses using lead-free glass in its lineup of 35 existing aspherical glass lenses for optical communications, including fiber to the home (FTTH) and submarine cable. Sample shipments will commence in April 2008.
NASA announced Thursday that members of the general public from around the world will have a chance to suggest a new name for the cutting edge Gamma-ray Large Area Space Telescope, otherwise known as GLAST, observatory before it launches in mid-2008. The satellite will observe some of the most powerful forces known in the universe.
In a study that could lay the foundation for mass-produced single-molecule sensors, physicists and engineers at Rice University have demonstrated a means of simultaneously making optical and electronic measurements of the same molecule.
Light pipes are becoming increasingly popular as a means of homogenizing, conducting and reshaping light for use in a wide range of optical equipment and assemblies.
