Scientists have for the first time devised a multi-pixel modulator for light waves at terahertz (THz, or 10^12 Hz) frequencies. The formal study of THz radiation, which can be described as far-infrared light, dates back many years, but has become increasingly widespread since around 1990, when efficient methods for generating and detecting the radiation become available. The expected applications include carrying out biological spectroscopy and imaging buried structures in semiconductors.
