BURLINGTON, Mass., Feb. 5 -- EM4 Inc., a supplier of optoelectronic manufacturing services and packaging technologies, has announced an $8 million Series B funding round that will contribute to its move into larger facilities, in Bedford, Mass., this month. EM4 has developed proprietary assembly tools that it says provides faster, more accurate and "more reproducible" fiber alignment at critical manufacturing stages. The process uses partial automation and provides a two-fold increase in capacity and throughput while improving yield, EM4 said. EM4 said the new 30,000-square-foot building will...Read full articleRelated content from Photonics MediaArticlesCritical Tech, Policy Priorities at the Fore of Second SPIE SummitPolicymakers and appointed officials outlined many of the U.S. government’s foremost priorities in science and technology, joining with leaders from the photonics sector in Washington, D.C.,...Photonics Spectra November 2023 IssueG&H Sells Boston Optoelectronics OperationPrecision optical technology manufacturer G&H has sold its Boston-based EM4 optoelectronics subsidiary to EMFOUR Acquisition Co.
