| Fully 3D-printed, flexible OLED display Posted: 07 Jan 2022 01:46 PM PST Researchers used a customized printer to fully 3D print a flexible organic light-emitting diode (OLED) display. The discovery could result in low-cost OLED displays in the future that could be widely produced using 3D printers by anyone at home, instead of by technicians in expensive microfabrication facilities. |
| Light–matter interactions simulated on the world’s fastest supercomputer Posted: 07 Jan 2022 07:10 AM PST Researchers have developed a computational approach for simulating interactions between matter and light at the atomic scale. The team tested their method by modeling light -- matter interactions in a thin film of amorphous silicon dioxide, composed of more than 10,000 atoms, using the world's fastest supercomputer, Fugaku. The proposed approach is highly efficient and could be used to study a wide range of phenomena in nanoscale optics and photonics. |
| Integrated photonics for quantum technologies Posted: 07 Jan 2022 07:10 AM PST An international team of leading scientists has compiled a comprehensive overview of the potential, global outlook, background and frontiers of integrated photonics. The paper is a roadmap for integrated photonic circuits for quantum technologies. The review outlines underlying technologies, presents the current state of play of research and describes possible future applications. |
| Seeking a way of preventing audio models for AI machine learning from being fooled Posted: 07 Jan 2022 05:44 AM PST Warnings have emerged about the unreliability of the metrics used to detect whether an audio perturbation designed to fool AI models can be perceived by humans. Researchers show that the distortion metrics used to detect intentional perturbations in audio signals are not a reliable measure of human perception, and have proposed a series of improvements. These perturbations, designed to be imperceptible, can be used to cause erroneous predictions in artificial intelligence. Distortion metrics are applied to assess how effective the methods are in generating such attacks. |
