GPD Optoelectronics was founded in 1973 as Germanium Power Devices Corp. We began by making high-quality germanium transistors, but since the early 1980’s we have earned our place as a trusted manufacturer of both germanium and indium gallium arsenide photodiodes.
As we gained experience, we grew our technical capabilities and production capacity, eventually doubling our size with a move to a new facility in Salem, NH.
