Physicists have developed a fast and sensitive mechanical tool to measure light. The graphene nanomechanical bolometer is the fastest and most sensitive in its class. It is poised to detect nearly every color of light at high speeds and obtain measurements at and far above room-temperature.
Read moreFirst demonstration of one petabit per second network node
Computer scientists have demonstrated the first large-scale optical switching testbed capable of handling 1 Petabit per second optical signals. This demonstration made use of state-of-the-art large-scale and low-loss optical switches based on MEMS technology, three types of next-generation spatial-division multiplexing fibers, and included data rates from 10 Terabit per second to 1 Petabit per second. This is a major step forward towards practical petabit-class backbone networks.
