Electro optical modulators (EOMs) are the main components in optical communication networks, which can control the amplitude, phase, and polarization of light through external electrical signals.In order to achieve ultra compact and high-performance EOM, most of today's research focuses on on-chip devices that combine semiconductor technology with state-of-the-art tunable materials. However,...
Zhao Yun/Columbia Engineering Company provided an advanced schematic of a photonic integrated chip, which aims to convert high-frequency signals into low-frequency signals using all optical frequency division.Scientists have built a small all optical device with the lowest microwave noise ever recorded on integrated chips.In order to improve the performance of electronic devices used for global n...
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, IPG Photonics, a leading company in the global fiber laser field, announced the official opening of its new office and central technology center in Japan, marking a solid step in the technology giant's strategic deployment in the Asia Pacific region.The opening of this new office not only demonstrates IPG Photonics' high regard for Japan and the entire Asia Pacific market, but also indic...
SpaceX and its billionaire CEO Elon Musk may finally have reason to look back in the satellite internet competition. On Thursday, Amazon revealed that it had successfully used a space laser technology called "Optical Intersatellite Link" to transmit connections between two Kuiper Program satellites in low Earth orbit, located 621 miles apart, at a speed of 100 gigabits per second. This is approxim...
