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,
