In 2006, Digital Optics was acquired in an amost entirely cash transaction by Tessera Technologies Inc. Founded ut of Unversity of North Carolina, Digital Optics had been using wafer-based manufacturing processes, analogous to integrated circuit manufacturing, to built an integrated micro-optical systems - a process adding improved functionality and reduced complexity to the creation of all-optical systems. Integrated Micro-Optical Systems (IMOS) could be used to build a wide range of modules and components, including collimated arrays for optical switching, integrated wavelockers for DWDM, transceivers and dispersion/compensator chips. The firm . A complete solutions provider with manufacturing infrastructure and additional outsourcing, applications include optics and optical subassemblies for data storage, communications, semiconductor equipment, bar-code scanning, consumer applications; and sensors for aerospace, medical, automotive and military.
