Optical Power Limiter Pushes Attack-Proof Quantum Communication Forward
SINGAPORE, July 19, 2021 — Researchers from the National University of Singapore (NUS) developed two methods to enable quantum key distribution (QKD) communications to avoid side-channel attacks — instances in which attackers exploit weaknesses in the setup of the...
Miniature Telescope Could Improve Lidar Performance, Advance Planar Optics
ORLANDO, Fla., July 16, 2021 — A University of Central Florida (UCF) team led by professor Shin-Tson Wu has developed a device made with cascaded liquid crystal (LC) flat optical elements, called a miniature planar telescope, that allows efficient, wide-angle, high-precision...
CMOS-Compatible Spectrotemporal Compressor Could Support Ultrafast Optical Signal Processing
SINGAPORE, July 14, 2021 — Researchers at the Singapore University of Technology and Design (SUTD), the A*STAR Institute of Microelectronics, and MIT have developed an all-optical spectrotemporal pulse compression system. The system, which is built on a CMOS-compatible...
Inverted Material Design Brings Reflective Screen into Focus
GOTHENBURG, Sweden, July 14, 2021 — Tungsten trioxide is the core material in a new type of reflective screen — sometimes described as “electronic paper” — that offers optimal color display and uses ambient light to keep energy consumption to a minimum. The new...
Cranial Windows Allow Simultaneous Imaging of the Brain’s Different Regions
WASHINGTON, D.C., July 13, 2021 — Researchers from Tsinghua University have developed a way to image multiple areas of the brain at the same time, both on the brain’s surface and deep inside the brain. Since brain processes often span multiple regions of the brain, researchers...
