Many materials emit light in ways that encode information in its polarization. According to researchers at École Polytechnique Fédérale de Lausanne (EPFL), Switzerland, polarization is key for future technologies, from quantum computers to secure communication and holographic displays.Among such phenomena is a form known as circularly polarized luminescence (CPL), a special type of light emission ...
According to scientists at MIT, mathematical formulas developed by MIT researchers and other institutions can significantly improve the sustainability of 3D printing.Issues with 3D printing of plastics3D printers typically use mass-produced polymer powders to print parts, which are consistent and predictable, but also difficult to recycle.Other more environmentally friendly options also exist and ...
Recently, a team from the National Key Laboratory of Ultra strong Laser Science and Technology at the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, collaborated with the Arctic University of Norway (UiT) to make progress in the efficient cracking of high-density polyethylene (HDPE) using strong laser molecular bond breaking technology. The research results were publ...
BAE Systems Australia has successfully conducted experiments at the Osborne Naval Shipyard and Henderson Shipyard, using laser scanning technology to create 3D models of pipelines that will be installed on the currently under construction Hunter class frigates.A one week trial was conducted at the Zero Line Future factory in southern Adelaide and BAE Systems Australia's Henderson Shipyard, demonst...
Light can calculate functions during propagation and interaction with structured materials, with fast speed and low energy consumption. The use of all optical neural networks for general computing requires an optical activation layer with nonlinear dependence on the input. However, existing optical nonlinear materials either have slow speeds or very weak nonlinearity at the level of natural light ...
