Optical sensors operating in the near infrared (NIR) are important for applications in imaging, photodetectors, and biological sensors. Notably, recent reports on the synthesis of high quality, large areas of graphene has ...
Tiny "black holes" on a silicon wafer make for a new type of photodetector that could move more data at lower cost around the world or across a datacenter. The technology, developed by electrical engineers at the University ...
Researchers in Singapore and China have collaborated to develop a self-powered photodetector that can be used in a wide range of applications such as chemical analysis, communications, astronomical investigations and much ...
Duke University researchers believe they have overcome a longstanding hurdle to producing cheaper, more robust ways to print and image across a range of colors extending into the infrared.
Researchers at Toyota Central R&D Labs describe the first all solid-state wavelength-dependent bipolar photodetectors with fast response times and tunable switching wavelengths. The findings are reported in Applied Physics ...
Data traffic is growing worldwide. Glass-fiber cables transmit information over long distances at the speed of light. Once they have reached their destination, however, these optical signals have to be converted into electrical ...
While infrared waves are available in short, mid, and long lengths, most detection devices are unable to harness all three at the same time.
Making an incredibly fast photodetector is one thing, but actually measuring its speed is another.
Researchers from FOM, the University of Amsterdam, the Delft University of Technology and the University of the Algarve have discovered that when light hits germanium nanocrystals, the crystals produce 'bonus electrons'. ...
(Phys.org) —UCLA researchers have developed a perovskite photodetector that could reduce manufacturing costs and improve the quality of medical and commercial light sensors.
