Sivers Optics, a subsidiary of Sivers Semiconductors, has signed a product development agreement with an undisclosed company.Starting from the initial contract worth $1.3 million, the prototype will be delivered in 2024, and it is expected that the agreement will grow rapidly in 2025 before transitioning to mass production. After entering full production, customers expect the annual chip productio...
Recently, the German research institution Fraunhofer ILT team is collaborating with the Department of Optical Systems Technology (TOS) at RWTH Aachen University to develop a testing system aimed at studying complex laser beam profiles using a new platform. This platform can construct customized beam profiles for laser powder melting (PBF-LB) 3D printing, thereby improving part quality, process sta...
1. Research backgroundDirected energy deposition (DED), as an efficient and economical technology in the field of additive manufacturing (AM), is widely used in the manufacturing of metal materials. However, its high heating and cooling rates, as well as significant temperature gradients, often lead to rapid solidification, forming cross layer columnar grains and internal defects, seriously affect...
Topological laser (TL) is a laser device designed and manufactured using the principles of topological optics, which can produce a robust single-mode laser and is an ideal light source for future new optoelectronic integrated chips. Electrically pumped topology lasers have become a research hotspot due to their small size and ease of integration, but topology lasers based on electrical injection a...
The most famous use of GPS satellites is to help people understand their location, whether it is driving cars, ships or planes, or hiking in remote areas. Another important but little-known use is to distribute information to other Earth observation satellites to help them accurately locate measurements of our planet.NASA and several other federal agencies, including the US Space Force, the US Spa...
