Google works with magic leap on AR optics and manufacturing

Recently, the research team of Chang Lin from the School of Electronics of Peking University and the research team of Li Wangzhe from the Aerospace Information Research Institute of the Chinese Academy of Sciences published a research article entitled "Microcomb synchronized optoelectronics" online in Nature Electronics, realizing the application of photonic chip clocks in information systems for ...

Scientists at the City University of New York use tiny nitrogen defects in the atomic structure of diamonds as "color centers" to write data for storage. This technology is published in the journal Nature Nanotechnology and allows for encoding multiple bytes of data into the same nitrogen defect at multiple optical frequencies, without confusing the information content.The common laser based techn...

Recently, researchers have developed a comb laser with higher stability and efficiency. The use of synthetic reflection self injection locking micro comb design enables the laser to achieve stability and increase conversion efficiency by more than 15 times. This efficient, stable, and easy to manufacture design is expected to make rapid progress in fields such as portable sensors, autonomous navig...

Engineers at the University of Pennsylvania have developed a new chip that uses light waves instead of electricity to perform complex mathematical operations necessary for training artificial intelligence. This chip has the potential to fundamentally accelerate the processing speed of computers while reducing their energy consumption.The design of a silicon photonic chip was the first to combine t...

The Chinese Academy of Sciences reduced the volume of the deep ultraviolet laser by 90% and achieved 193 nm vortex beam output for the first time. Professor Xuan Hongwen described "loading truck equipment into the car trunk". This technology enables a 30% reduction in the size of lithography features, breaking through the bottleneck of the 2-nanometer process. In the next three years, laser power ...
