u2t Innovative Optoelectronic Components was founded by Andreas Umbach, Günter Unterbörsch, and Dirk Trommer as a spin-off company of the Heinrich-Hertz-Institut für Nachrichtentechnik Berlin GmbH, the "Center of Excellence for Indium Phosphide Technology" in Germany, at the beginning of 1998. The three scientists are recognized experts in the field of indium phosphide (InP)-based optoelectronic devices, especially on photonic integrated photoreceivers. In 1997 they realized an increasing commercial interest in the devices resulting from their research at HHI.

The intention of the company is to manufacture and commercialize state-of-the-art opto-electronic components as a direct transfer from the research labs to the market place in order to support R&D-engineers working on fibre-optic communication systems and networks. As first products ultrafast waveguide-integrated photodetector chips and modules have been offered. As a next step the product spectrum will be extended to offer integrated photoreceivers additionally comprising HEMT-based amplifiers.
