Customized laser beams focused through transparent glass can generate a small dot inside the material. Researchers from Northeastern University have reported a method of using this small spot to improve laser material processing and increase processing resolution.Their research results are published in the journal Optics Letters.Laser processing, like drilling and cutting, is crucial in industrie...
Summary:To filter out infrared light from the driving light source in the extreme ultraviolet lithography (EUVL) light source system, a rectangular grating structure needs to be fabricated on the surface of the collection mirror. However, the collection mirror grating usually undergoes deformation during the manufacturing process, resulting in a decrease in filtering efficiency. The process errors...
PhotonVentures, based in Eindhoven, the Netherlands, has announced the launch of a venture capital fund designed to help early-stage photonic chip startups and scale-up businesses.In the first round of funding, PhotonDelta, a Dutch photonic integrated circuit (PIC) pioneer, raised €60 million as the lead investor and numerous private investors. PhotonVentures said it plans to raise a total of...
