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...
Surface acoustic wave technology is renowned for its high precision and fast driving, which is crucial for microfluidics and affects a wide range of research fields. However, traditional manufacturing methods are time-consuming, complex, and require expensive cleanroom facilities.A new method overcomes these limitations by utilizing aerosol jet printing to create customized equipment with various ...
Recently, scientists used laser gyroscopes to measure that the change in Earth's rotational speed is less than one millionth. This technology can help scientists understand the complex flow of water and air, which can cause the smallest adjustments to the Earth's rotation.The Earth's rotation is not completely stable. Planets accelerate or slow down as they rotate, slightly shortening or prolongin...
A researcher from Aston University in Birmingham, UK, has received a grant of £ 625000 (approximately $850000) to help address the energy surge required for data centers.The UK’s Royal Academy of Engineering has announced the latest recipients of its fellowships which support engineers to solve a wide range of society’s challenges. Data center energy demand is described as “one of today’s most pre...
A team of computer and electrical engineers at UC Santa Barbara, in collaboration with several colleagues at Caltech and another colleague at Anello Photonics, has developed a first-of-its-kind chip that can carry both laser and photonic waveguides. In a paper published in the journal Nature, the team describes how they made the chip and how it worked during testing.With the advent of integrated c...
