An ultra-fast and ultra-small optical switch has been invented that could advance the day when photons replace electrons in the innards of consumer products ranging from cell phones to automobiles.
Imagine that you are in a meeting with coworkers or at a gathering of friends. You pull out your cell phone to show a presentation or a video on YouTube. But you don't use the tiny screen; your phone projects a bright, clear image onto a wall or a big screen. Such a technology may be on its way, thanks to a new light-bending silicon chip developed by researchers at Caltech.
A team of MIT researchers has used a novel material that's just a few atoms thick to create devices that can harness or emit light. This proof-of-concept could lead to ultrathin, lightweight, and flexible photovoltaic cells, light emitting diodes (LEDs), and other optoelectronic devices, they say.
Most modern electronics, from flat-screen TVs and smartphones to wearable technologies and computer monitors, use tiny light-emitting diodes, or LEDs. These LEDs are based off of semiconductors that emit light with the movement of electrons. As devices get smaller and faster, there is more demand for such semiconductors that are tinier, stronger and more energy efficient.
Lightwave Logic, Inc., a technology company focused on the development of Next Generation Photonic Devices and Non-Linear Optical Polymer Materials Systems for applications in high speed fiber-optic data communications and optical computing, announced today that it has begun the process of manufacturing its advanced design Silicon Organic Hybrid Transceiver prototype and has released the completed chip design to OpSIS Inc., who will be producing initial silicon wafers. Delivery of the wafers is expected in early summer.
Mark Stockman, physics professor and director for the Center for Nano-Optics at Georgia State University, has been elected a SPIE fellow for his achievements in theoretical nano-optics and nanoplasmonics.
A team of researchers from National University of Singapore (NUS) have created the first two-photon, small molecule fluorogenic probe that can serve as a useful tool for the rapid assessment of an individual's potential risk for Parkinson's disease.
University of Cincinnati researchers are discovering how to manipulate light to one day better view the world’s tiniest objects through a super-lens, as well as how to hide an object in plain sight. Masoud Kaveh-Baghbadorani, a doctoral student in the University of Cincinnati’s physics program, will present this research on March 4, at the American Physical Society Meeting in Denver.
As science and technology go nano, scientists search for new tools to manipulate, observe and modify the "building blocks" of matter at the nanometer scale. With this in mind, the recent publication in Nature Nanotechnology in which ICFO researchers demonstrate for the first time the ability to use near-field optical tweezers to trap a nano-size object and manipulate it in the 3 dimensions of space, is an exciting achievement.
Göttingen-based scientists working at DESY's PETRA III research light source have carried out the first studies of living biological cells using high-energy X-rays. The new method shows clear differences in the internal cellular structure between living and dead, chemically fixed cells that are often analysed.
