Terahertz Photonics breakthroughs promise ultrahigh speed communication systems to medical imaging and diagnostics, industrial quality control, and security screening

Terahertz (THz, 1012 Hz) technology is based on light sources with frequencies much lower than of visible light, and slightly higher than of microwaves. Such light sources have a number of unique capabilities, for example that it can propagate through most insulating materials such as paper, plastic, cardboard, clothes etc., while being highly sensitive to…
