Liquid crystal elastomers are expected to be applied in displays, sensors, smart devices, and wearable devices.A team from POSTECH University in South Korea, led by Professor Su Seok Choi and Professor Seungmin Nam, has developed a new type of stretchable photonic device that can control the wavelength of light in various directions.This work was carried out by the Department of Electrical Enginee...
Recently, TRUMPF, a leading global provider of machine tools and laser technology solutions, released preliminary data for the 2023/24 fiscal year: compared to the previous fiscal year, sales decreased by about 4% year-on-year to 5.2 billion euros; The order amount decreased by 10% to 4.6 billion euros. The Tongkuai Group ended its 2023/24 fiscal year on June 30, 2024, with a decrease in both s...
Recently, a team led by Gao Chunqing and Fu Shiyao from the School of Optoelectronics at Beijing University of Technology combined optical spatial coordinate transformation with photon spin Hall effect to construct a photon angular momentum filter for the first time internationally, achieving on-demand regulation of photon spin angular momentum and orbital angular momentum.The related achievements...
Recently, Laserline, a leading semiconductor laser manufacturer in Germany, announced that it has completed the acquisition of a 70% stake in WBC Photonics, a Boston based laser technology expert, marking a significant strategic expansion for Laserline. Through this transaction, Laserline not only expands its product portfolio to include blue laser systems with excellent beam quality (better tha...
Researchers have shown that dissipative Kerr solitons (DKS) can be used to create chip based optical frequency combs with sufficient output power for optical atomic clocks and other practical applications. This progress may lead to chip based instruments being able to perform precise measurements that were previously only possible in a few specialized laboratories.Gr é gory Moille from the ...
