Short-wave infrared radiation (SWIR) is roughly the part of the electromagnetic spectrum between 1.4 μm – 3 μm, or 100 THz – 214 THz. This places it between visible light and microwaves ...

Prof Zhang Zhiyong’s team developed a heterojunction-gated field-effect transistor (HGFET) that achieves high sensitivity in short-wave infrared detection, with a recorded specific detectivity above ...

To him it means Liberty and Truth. This autumn, amid the happy local noise of a new U.S. radio season, the man at the other end of U.S. short-wave transmission was much on the minds of U.S ...

S. toyed with the notion of setting up a Federal short-wave station, abandoned the idea when private broadcasters, led by NBC, clamored for a chance to take Latin America by the ears. Since then ...

Current laser technologies for the extended short-wave infrared (SWIR) spectral range rely on expensive and complex materials, limiting their scalability and affordability. To address these challenges ...

Short-wave infrared radiation (SWIR) is roughly the part of the electromagnetic spectrum between 1.4 μm – 3 μm, or 100 THz – 214 THz. This places it between visible light and microwaves ...

Researchers have developed a new laser technology using large colloidal quantum dots of lead sulfide to emit coherent light in the extended short-wave infrared range. This innovation promises cheaper, ...
