The surface emission from a bulk semiconductor at ultra-low temperature and magnetic carrier confinement was reported by Ivars Melngailis in 1965. The first proposal of short VCSEL was done by Kenichi Iga of Tokyo Institute of Technology in 1977. A simple drawing of his idea is shown in his research note. Contrary to the conventional Fabry-Perot edge-emitting semiconductor lasers, his invention comprises a short laser cavity less than 1/10 of the edge-emitting lasers vertical to a wafer s.

The semiconductor-based Vertical-External-Cavity Surface-Emitting Laser (VECSEL) technology from Vexlum solves a major problem in high-tech industries: the absence of small, affordable, high-power laser sources at specific wavelengths. TAMPERE, Finland (February 5, 2026) Vexlum, a manufacturer of advanced semiconductor lasers for high-impact applications, has announced it has secured EUR 10 million in funding to scale its proprietary semiconductor chip manufacturing and laser technology operations in Finland. Originating as a spin-off from the Optoelectronics Research Centre at Tampere University of Technology in Finland, the company brings deep expertise in epitaxy, optoelectronic. As a dedicated VCSEL (Vertical-Cavity Surface-Emitting Laser) manufacturer, Ace Photonics Co. focuses on high-performance semiconductor lasers in the 750–1550 nm range, serving industrial, quantum and R&D applications. Vexlum claims that this funding is set to be.

In, wavelength-division multiplexing (WDM) is a technology which a number of signals onto a single by using different (i.e., colors) of. This technique enables communications over a single strand of fiber (also called wavelength-division duplexing) as well as multiplication of capacity.
The Cable Tray Slope & Fabrication Calculator is a field-ready tool for electrical construction workers who need to quickly calculate V-cut dimensions, bolt hole positions, slope length, and hanger spacing for inclined cable tray installations. Watch how a skilled fabricator professionally marks a cable tray before cutting it with a grinder, ensuring accuracy, safety, and a clean final finish. Select the bend direction (vertical or horizontal). In this video, we'll cover the essential steps of marking and cutting cable trays. A laser marking machine is a specialized tool that uses concentrated light to permanently etch or mark. In the cable tray manufacturing industry, these two goals are often challenged by the need for precise identification, fast processing, and long-term durability of markings. Traditional marking methods like inkjet or mechanical engraving often fail to deliver permanent, high-resolution results. The bends, tees, crosses, risers and reducers of wire mesh cable tray can be easily and quickly made live at the project by using a bolt cutter.
