Optics, Photonics, & Lasers

A new device could open new avenues for the generation of high-frequency radiation with applications in science, radar, communications, security and medical imaging.

A lot of people think that high-energy lasers, or HELs, can't penetrate fog, rain and dust, said Thomas Webber, director of the Directed Energy Division's Technical Center,...

A single antenna can be used for both transmission and reception. To accomplish this, the transmission must be isolated from the reception. In Figure 1, a radio frequency...
