The ultrabroadband infrared frequency comb could be used for chemical detection in portable spectrometers or high-resolution remote sensors. (Nanowerk News) Optical frequency combs are specially ...
New ultrafast method for controlling magnetic materials might enable next-generation information processing technologies. This illustration shows that a pair of intense THz laser pulses drives spin ...
A frequency-agile meta-material that for the first time can be tuned over a range of frequencies in the so-called "terahertz gap" has been engineered. The team's first-generation device achieved 20 ...
Ultrabroadband IR frequency comb could be used for detection in portable spectrometers. The comb uses a double-chirped mirror. Researchers at MIT have demonstrated a compact, fully integrated ...
The terahertz segment of the electromagnetic spectrum exists in a sort of “twilight zone” between about 300 GHz (0.3 THz) to 3 THz (note that the upper boundary value is somewhat arbitrary, and some ...
Engineers took an early step toward building superfast computers that run on far-infrared light instead of electricity: They made waveguides -- the equivalent of wires -- that carried and bent this ...
