Science: Toward Bridging the Terahertz Gap with Silicon-Based Lasers

Friday, April 29th, 2005

A laser emitting at terahertz wavelengths (30 to 300 mum or 1 to 10 THz) would be highly useful in medical and security applications, but current terahertz lasers are complex and expensive. In his Perspective, Borak discusses recent advances toward building a more practical, silicon-based terahertz laser, which would be compatible with the ubiquitous silicon technology. Currently, so-called quantum cascade lasers look like most promising, but a working silicon quantum cascade laser is still some way off.

Scientists control super fast frequencies

Monday, April 18th, 2005

Imagine an imaging technology that could see deep into human tissue without the harmful side effects of radiation. Super-fast oscillations of radio waves, called terahertz (THz) have that promise, but so far, controlling them has been beyond reach.

Genomics and proteomics to increase the efficiency of drug discovery and development

Tuesday, April 5th, 2005

While the United Sates is still the world leader, Europe is having a good deal of success in the field of advanced genomics and proteomics research. Significant government funding together with the presence of large pharmaceutical companies has made Europe a major competitor in the efforts to deploy genomics and proteomics as vital tools in drug discovery and development.
