  1. 'Black Holes' In Silicon Enable High-Speed Photodetector

    Electrical engineers at University of California, Davis, and Silicon Valley startup W&WSens Devices have developed a new type of photodetector that relies on tiny, tapered "black holes" on a silicon wafer to trap light. Such a high-speed, high-efficiency photodetector can better handle the growing volumes of data traffic and higher bandwidths in data centers today.

  2. Sub-Nanosecond RF Signal Control Can Provide Wider Bandwidth

    Researchers at the University of Sydney have developed a new technique to control radio frequency (RF) signals on an integrated photonic chip at tuning speeds faster than a nanosecond. The achievement could alleviate bandwidth limitations caused by a growing number of interconnected wireless devices.

  3. Samsung Unveils 4K HDR Display For the Silver Screen

    Samsung Electronics has unveiled what it claims as the world's first High Dynamic Range LED theater display at the CinemaCon 2017 conference in Las Vegas.

  4. BYU Researchers Develop Flexible Glass For Microfluidic Nanodevices

    Researchers at Brigham Young University (BYU) have developed a new method to fabricate flexible nano-scale membranes using surface micromachining and silica thin films. 

  5. Graphene Harvests Solar Energy To Power ‘Electronic Skin’

    University of Glasgow researchers have developed a layer of graphene that can harvest sunlight to power 'electronic skin,' whose development holds much promise in the fields of prosthetics and robotics.

  6. Lockheed Martin Readies 60 kW Fiber Laser Weapon For U.S. Army

    Lockheed Martin says it is set to deliver a 60 kW fiber optic laser weapon to the U.S. Army, which intends to mount it atop tactical ground vehicles to neutralize enemy drones, rockets, and mortars.

  7. Li-Fi System 100 Times Faster Than Wi-Fi

    A new type of Li-Fi (Light Fidelity) optical wireless system being developed by students at Eindhoven University of Technology (TU/e) Institute for Photonic Integration is up to 100 times faster than the best Wi-Fi connections available.

  8. X-Rays Create 3D Images Of A Microchip’s Interior

    It’s the first time a non-destructive method has clearly visualized the paths of a chip’s internal wiring (just 45 nanometres — 45 millionths of a millimetre — wide) and its 34-nanometre-high transistors without distortions or deformations.

  9. Ultrafast Recording Of Microstructural Alteration By Femtosecond Lasers

    Scientists at the University of Rochester have developed a scattered-light-based optical imaging technique to record, for the first time, the complete process by which a material's surface is transformed by laser beams to such extent that the materials exhibit new and useful properties. 

  10. Photonic Doping Makes Metamaterials Fabrication Easier

    University of Pennsylvania engineers have developed a new technique called photonic doping to design and more easily fabricate electromagnetic metamaterials.
