Sheaumann Laser, Inc. is a privately owned corporation founded in 2005 by Jim Hsieah, a pioneer in the development of 1.3 µm and 1.5 µum semiconductor lasers using quaternary materials, whose company, Lasertron, became a leading producer of lasers during the fiberoptic telecommunications boom of the 1980’s and 1990s. In 2015, Sheaumann merged with Axcel Photonics (also owned by Hsieh since 2004), which added epitaxial growth and wafer processing capabilities to Sheaumann’s design and packaging competencies. A 2019 grant from the Massachusetts Manufacturing Innovation Initiative enabled Sheaumann to expand its wavelength range capabilities and relocate to its new headquarters, where it also has a photonics incubator space. At a time when laser manufacturing companies are frequently changing ownership and moving production overseas, Sheaumann’s leadership team continues to stay constant and uphold its vision of keeping manufacturing in the US.
