Significant progress made in 808nm high-power semiconductor laser chips

Nikon Vision, a subsidiary of Nikon Corporation, is pleased to announce the launch of the COOLSHOT 20i GIII laser rangefinder for golfers, which is Nikon's small and lightweight model in the COOLSHOT series.While maintaining the lightweight and compact size of the COOLSHOT 20i GII, the new model notifies users through brief vibrations that the distance to the flagpole has been measured.When measur...

Recently, Dong Yibo, from the Photonic Chip Research Institute of Shanghai University of Technology, published his research findings titled "Nanoprinted Diffractive Layer Integrated Vertical Cavity Surface Emitting Vortex Lasers with Scalable Topological Charge" as the first author in the internationally renowned journal Nano Letters.This achievement was jointly completed by the team of academicia...

Recently, optical semiconductor developer Lumiotive, headquartered in Seattle, USA, launched a new LiDAR sensor LM10, which is its first fully produced product of light controlled metasurface (LCM) technology designed for digital beam steering.The developers stated that compared to mechanical systems, their digital beam steering method overcomes the limitations of traditional LiDAR sensors in term...

Us researchers report 8.1 μm wavelength quantum cascade laser (QCL) grown on silicon (Si) by MOCVD [S. Xu et al., Applications. Physics Letters, v123, p031110, 2023]. "There are no previous reports of QCL growth on silicon substrates by metal-organic chemical vapor deposition (MOCVD)," commented the team from the University of Wisconsin-Madison, the University of Illinois at Urbana-Champaign an...

T35 multi-core fiber grating and T103 multi-core fiber grating arrays can be engraved into all fiber cores in physical locations, or only onto certain fiber cores.They can also have the same wavelength, or they can have all different wavelengths at the same physical location along the fiber or at different physical locations along the fiber.T35 and T103 are very suitable for projects that require...
