Limiting Auger recombination enables “record” quasi-continuous wave laser output.For years, engineers have sought better ways to build tiny, efficient lasers that can be integrated directly onto silicon chips, a key step toward faster, more capable optical communications and computing.Today’s commercial lasers are mostly made from III-V semiconductors grown on specialized substrates—a process that...
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...
Researchers at the University of Illinois at Urbana Champaign have developed compact visible wavelength achromatic mirrors using 3D printing and porous silicon, which are crucial for miniaturization and lightweight optical devices. These high-performance hybrid micro optical devices can achieve high focusing efficiency while minimizing volume and thickness. In addition, these microlenses c...
Tesat Spacecom's laser communication terminal announced on October 26th that the company has passed critical ground testing deployed on NASA satellites.Tesat's SCOTT80 optical terminal was selected by Lockheed Martin, one of several manufacturers producing satellites for the Space Development Agency.SDA is an agency under the United States Space Force that plans to deploy a network of interconnect...
Quantum optics is a complex field where theoretical and experimental physicists collaborate to achieve breakthroughs in explaining subatomic level phenomena.Recently, Farokh Mivehvar from the University of Innsbruck used the most comprehensive model in quantum optics, the Dicke model, to study the interaction between two groups of atoms in a quantized field. This new study makes it possible to obs...
