As the military, science agencies, and communications firms compete for scarce spectrum resources, researchers at Harvard, MIT, and the Army have developed a compact, room temperature, widely tunable terahertz laser that offers the potential for high-bandwidth communications, ultrahigh-resolution imaging, and precise long-range sensing for radio astronomy. Until now, the terahertz section of the electromagnetic spectrum,
Researchers have nearly doubled the continuous output power of a type of laser, called a terahertz quantum cascade laser, with potential applications in medical imaging, airport security and more. Increasing the continuous output power of these lasers is an important step toward increasing the range of practical applications. The researchers report their results in the
A new type of semiconductor laser has been created using the unique electronic properties of graphene. Designed in the UK by researchers at the University of Manchester, the prototype operates in the terahertz band and can be easily tuned to output radiation at specific wavelengths. The team says that its research could lead to the
