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...
The latest expansion of the European Space Agency's laboratory is essentially portable: this European Space Agency's mobile optical ground station is housed in a standard container and can be transported throughout Europe as needed for laser based optical communication with satellites - including NASA's Psyche mission, in space millions of kilometers away.The station has officially become a part o...
A research team in France has reported a novel laser that emits light in the orange region of the spectrum, indicating its potential applications in flow cytometry and astronomical laser guidance.In the research results just published in Optics Express, the team (including researchers from the É cole Polytechnique in Caen, France and Oxxius, a laser manufacturer based in Lannion) claimed that the ...
Recently, the team from the State Key Laboratory of Intense Field Laser Physics, Shanghai Institute of Optics and Mechanics, Chinese Academy of Sciences found that the third-order harmonics induced by air filamentation of high repetition rate femtosecond lasers have significant self jitter. To solve this bottleneck problem, a solution based on an external DC electric field was proposed, which sign...
Ultra short laser pulses for local welding (Source: Fraunhofer IOF)With the accelerated evolution of electronic devices towards high power, high frequency, and miniaturization, ceramic substrates have become core materials in fields such as power semiconductors, 5G communications, and new energy vehicles due to their excellent thermal conductivity, insulation, and high temperature resistance.
