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,
DARPA starts new program to explore whether electromagnetic waves are purposefully transmitted and received within or between cells and, if so, to leverage those insights not just for biosystems but also for communicating in cluttered electromagnetic environments. For decades scientists have wondered whether electromagnetic waves might play a role in intra- and inter-cell signaling. Researchers
Photonics, the technology that helps drive today’s telecommunications systems, offers major advances in the area of signal transmission. Researchers at the Georgia Tech Research Institute (GTRI) are adapting optical techniques from the photonics telecom arena to enhance U.S. electronic warfare (EW) capabilities. Optical approaches provide greatly increased frequency coverage and long distance low-loss transfer of
