Let's create more together



GPD Optoelectronics is a family-owned business that was founded in 1973 as Germanium Power Devices Corp. We started out making germanium transistors, but since the early 1980’s we have earned our place as a trusted manufacturer of germanium and InGaAs 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.

Despite our growth, we remain committed to the values that made us successful. We believe that by operating with integrity and trust we drive constant organizational improvement, which strengthens our relationships with our employees and customers. Customer satisfaction remains our highest priority, so we strive to deliver high-quality products on time, and provide unparalleled service, responsiveness, and collaboration. While we offer a variety of off- the-shelf products for customers with pressing delivery needs, we specialize in providing customized parts that are uniquely tailored to your application. Need something a little different? We have the agility to design and deliver prototypes of custom products, often within just a few weeks.

The process starts with our innovative engineering team and in-house wafer design and processing. From there, with our skilled machinists and and 3D printing capabilities, we can adapt to a variety of design requirements. We maintain class 1,000 and 10,000 clean rooms in our production facilities, and have hermetic sealing capability as well as automated assembly and testing. GPD maintains an inspection system in accordance with MIL-I-45208. Photodiodes are subjected to Telcordia testing requirements (TA-NWT-00093), MIL-STD-883 test methods and/or customer specifications.

We are proud to be a trusted partner from the design stages through the life cycle of your product.
