Polarization-insensitive metasurface lenses (metalenses) sort primary colors on high-density pixels without the use of color filters. The metalenses simultaneously act as pixel-scale color splitters and lenses and are compatible with complementary metal–oxide-semiconductor sensor technology. An image sensor with such metalenses significantly enhances the detected light power, while affording high image quality, incident angle tolerance, and …
Researchers at Princeton University and the University of Washington have developed an ultracompact camera the size of a coarse grain of salt. The system relies on a technology called a metasurface, which is studded with 1.6 million cylindrical posts and can be produced much like a computer chip. Impacts: * Next level miniturization * better …
Researchers at the University of Nottingham have developed an ultrasonic imaging system, which can be deployed on the tip of a hair-thin optical fibre, and will be insertable into the human body to visualise cell abnormalities in 3D. The new technology produces microscopic and nanoscopic resolution images that will one day help clinicians to examine …
Researchers demonstrate an on-chip, optoelectronic device capable of sampling arbitrary, low-energy, near-infrared waveforms under ambient conditions with sub-optical-cycle resolution. The detector uses field-driven photoemission from resonant nanoantennas to create attosecond electron bursts that probe the electric field of weak optical waveforms. Using these devices, they sampled the electric fields of ~5 fJ (6.4 MV m−1), few-cycle, near-infrared waveforms …
The birthplace of the photonics revolution may well be named after lithium niobate. While, Lithium Niobate Valley doesn’t have the same ring as Silicon Valley, this material could be for optics what silicon was for electronics. Lithium niobate is already one of the most widely used optical materials, well-known for its electro-optic properties, meaning it …
INRS researchers have achieved a breakthrough in a light-weight photonic system created using on-chip devices and off-the-shelf telecommunications components. They demonstrated that photons can become an accessible and powerful quantum resource when generated in the form of color-entangled quDits. The system uses a small and cost-effective photonic chip fabricated through processes similar to those used …
HPE announced that it has created the largest single-memory computing system the world has ever seen, capable of holding 160 terabytes of data. In 2014, HPE introduced The Machine research project—the largest and most complex research project in our company’s history—designed to deliver the world’s first Memory-Driven Computing architecture. They believe this new computer will …
Here is a link to a 16 page unclassified Summary of A Threat to America’s Global Vigilance, Reach, and Power High-speed maneuvering weapons The U.S. lead in the technologies of high-speed flight is in question, particularly as it pertains to military applications. Several countries around the world have been quite busy establishing their own capabilities, …
China’s largest carrier rocket, the Long March-5, will make its first trip into space in early November this year. The rocket, which arrived at the Wenchang launch center in south China’s Hainan Province in September, was transported to the launch area on Friday morning, after finishing final assembly and tests, said the State Administration of …
With a new irrigation system that waters a little-but-often an almond farmer uses 20% less water than he used to. Growing a single almond used to consume around a gallon of water. This is merely an American gallon of 3.8 liters. So now it is about 0.95 liters. Moisture sensors planted throughout almond nut groves …
NASA announced that they’d awarded defense giant Lockheed Martin a $20 million contract for 17 months of preliminary development on a quiet supersonic plane. The return of supersonic passenger air travel is one step closer to reality with NASA’s award of a contract for the preliminary design of a “low boom” flight demonstration aircraft. This …
