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 ...
The new architecture based on metamaterials provides a promising platform for constructing large-scale production and reprogrammable solutions that can perform computational tasks using light.The idea of simulating computers - a device that uses continuous variables instead of zero sum ones - may evoke outdated machinery, from mechanical watches to bomb sight devices used in World War II. But emer...
The University of California, Los Angeles is joining LaserNetUS, a high-power laser facility alliance established by the Department of Energy, aimed at advancing laser plasma science.Unique facilities are located in universities and national laboratories across the United States and Canada, providing a wide range of opportunities for researchers and students.The Phoenix Laser Laboratory at the Uni...
Ditzingen, 05. March 2025 – At its in-house exhibition INTECH, high-tech company TRUMPF is showcasing a new cooler for its laser cutting machines. The new unit is capable of reducing energy consumed during the cooling process and uses fifty percent less energy than conventional solutions. Unlike conventional coolers, the main components of this new solution— such as pumps, fans and compressors— ar...
Recently, a research team led by Professor Cai Wei and Professor Xu Jingjun from the School of Physical Sciences at Nankai University has experimentally confirmed for the first time the generation of polaritons, also known as Smith Purcell radiation, at the two-dimensional scale, and further demonstrated the ability of free electrons to regulate two-dimensional Smith Purcell radiation. The researc...
