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...
Exploring the propagation and localization of waves in various media has always been a core focus of optics and acoustics. Specifically, in photonics and phononics, scientists have been dedicated to understanding and controlling the behavior of light and sound waves in periodic media.Photonic crystals have unique bandgap characteristics, providing an excellent platform for studying wave propagatio...
Recently, DIT, a well-known semiconductor and display equipment manufacturer in South Korea, announced that the company has signed an agreement worth 20.52 billion Korean won to supply wafer processing equipment to SK Hynix. According to DIT, the equipment supplied to SK Hynix this time is mainly a laser annealing kit. DIT was founded in 2005 and was listed on KOSDAQ in 2018. Its main focus is o...
The ZEUS laser at the University of Michigan recently achieved a breakthrough of doubling the peak power of the strongest laser in the United States through its first 2 quadrillion watt experiment. Although this instantaneous power only lasts for 25 attosecond (one billionth of a second), it exceeds the total power of the global power grid by more than a hundred times.Karl Krushelnick, director of...
Recently, Tong Cunzhu, the research team of the Chinese President of Science, Chunguang Institute of Mechanical Mechanics, made important progress in the research field of photonic crystal surface emitting lasers (PCSEL), proposed a three lattice structure and achieved a low threshold 1550nm PCSEL. Relevant achievements were published in Light: Science and Application vol.13, 442024, and the famou...
