Terahertz Laser to Power “T-ray” Vision and High-Bandwidth Communications

As the military, science agencies, and communications firms compete for scarce spectrum resources, researchers at Harvard, MIT, and the Army have developed a compact, room temperature, widely tunable terahertz laser that offers the potential for high-bandwidth communications, ultrahigh-resolution imaging, and precise long-range sensing for radio astronomy. Until now, the terahertz section of the electromagnetic spectrum,

Hidden Properties of Solids

Physicists open the door to the first direct measurement of Berry curvature in solid matter. Berry curvature may not be the most well-known scientific concept, but to many physicists, its direct measurement is something akin to a holy grail. A powerful unifying principle in several branches of classical and quantum physics, Berry curvature is a

Scientists Report First Data Transmission Through Terahertz Multiplexer

Researchers have demonstrated the transmission of two separate video signals through a terahertz multiplexer at a data rate more than 100 times faster than today’s fastest cellular data networks.
