Prof Zhang Zhiyong's team at Peking University developed a heterojunction-gated field-effect transistor (HGFET) that achieves high sensitivity in short-wave infrared detection, with a recorded ...

Understanding electro-optical sensors is key to enhancing defense technology and how these passive devices convert light into ...

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 ...

As great as cameras that operate in the visual light spectrum are, they omit a lot of the information that can be gleaned from other wavelengths. There is also the minor issue that visibility is ...

The James Webb Space Telescope has captured a mid-infrared picture of Sagittarius A*, filling in a long-standing gap in ...
