Light can come in many frequencies, only a small fraction of which can be seen by humans. Between the invisible low-frequency radio waves used by cell phones and the high frequencies associated with ...

While the light of an ordinary laser only has one single, well-defined wavelength, a so-called ''frequency comb'' consists of different light frequencies, which are precisely arranged at regular ...

Wireless electronics that have been used thus far in next-generation mobile communications using terahertz waves may reach their technical limit (namely, upper limit of frequency for wireless ...

Optical frequency combs are specially designed lasers that act like rulers to accurately and rapidly measure specific frequencies of light. They can be used to detect and identify chemicals and ...

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 ...

Cambridge, MA – Optical frequency combs are specially designed lasers that act like rulers to accurately and rapidly measure specific frequencies of light. They can be used to detect and identify ...

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 ...
