#Computing at the speed of light University of Utah engineers have taken a step forward in creating the next generation of computers
and mobile devices capable of speeds millions of times faster than current machines. The Utah engineers have developed an ultracompact beamsplitter--the smallest on record--for dividing light waves into two separate channels of information.
The device brings researchers closer to producing silicon photonic chips that compute and shuttle data with light instead of electrons.
Electrical and computer engineering associate professor Rajesh Menon and colleagues describe their invention today in the journal Nature Photonics Silicon photonics could significantly increase the power and speed of machines such as supercomputers

This particular electromagnetic spectral range of LWIR is important for a range of applications such as LIDAR (light radar) systems,
basically because LWIR waves are highly transparent in earth atmosphere. This wave range also has great application for the soldiers in the military who rely on infrared thermal imaging technology and for flexible night vision glasses.
