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.

A cable tray vertical bend is a factory-formed or field-fabricated component used to change the elevation path of a cable tray system by 90° in the vertical plane—either outside (turning outward, like a downward elbow) or inside (turning inward, like an upward step). The analysis includes structural types (ladder, perforated, wire mesh), specific bend fittings (horizontal and vertical risers). Calculate cable tray offset dimensions, bend section length, and horizontal run for obstacle routing Two Bends Per Offset: Every offset requires two equal bends — one to move laterally and one to return to parallel. The total tray section consumed = 2 × single bend length. Measure this distance along the straight tray. Ladder Rack Curved Sections (cULus Classified) provide a vertical (plane) change in direction. with a material of Steel colored Black.
