Scientists at Tokyo Institute of Technology have fabricated a multiplexer/demultiplexer module based on a property of light that was not being exploited in communications systems: the optical vortex. Such devices will be crucial for improving optical networks, which are the backbone of today’s Internet, so that they can meet the traffic demands of tomorrow.

Were Greek temples oriented towards aurorae?
Here we present selected parts of the published paper “Were Greek temples oriented towards aurorae?“, by Ioannis Liritzis & Helen Vassiliou. Continue reading “Were Greek temples oriented towards aurorae?”
Spectroscopy on individual molecules
While spectroscopic measurements are normally averaged over myriad molecules, a new method developed by researchers at the Technical University of Munich (TUM) provides precise information about the interaction of individual molecules with their environment. This will accelerate the identification of efficient molecules for future photovoltaic technologies, for example. Continue reading “Spectroscopy on individual molecules”
Laser physics: Attosecond photoelectron spectroscopy accelerated
Laser physicists have succeeded in reducing the acquisition time for data required for reliable characterization of multidimensional electron motions by a factor of 1000. Continue reading “Laser physics: Attosecond photoelectron spectroscopy accelerated”

New material, manufacturing process use sun’s heat for cheaper renewable electricity
Solar power accounts for less than 2 percent of U.S. electricity but could make up more than that if the cost of electricity generation and energy storage for use on cloudy days and at nighttime were cheaper.
