GPD Optoelectronics: Decades of Optical Innovation
GPD Optoelectronics has been advancing photodetector technology since its founding in 1973 as Germanium Power Devices Corp. What began as a manufacturer of high-quality germanium transistors quickly evolved into a leader in optoelectronic solutions.
Since the early 1980s, GPD has built a strong reputation for designing and producing germanium and indium gallium arsenide (InGaAs) photodiodes, as well as multi-element photodetectors for a wide range of demanding applications.
As our expertise and capabilities expanded, so did our operations—culminating in a move to a larger, state-of-the-art facility in Salem, New Hampshire, where we continue to innovate and grow today.
Our Core Values Are Found In A Commitment To Excellence
At the heart of GPD’s success is a commitment to our core values: innovation, quality, integrity, and community. We believe that operating with transparency and trust fosters continuous improvement and strengthens long-term partnerships with our customers and employees. Our mission—“Sensing Further Together”—reflects our collaborative approach to solving complex challenges. Customer success is our highest priority, and we are dedicated to delivering reliable, high-performance products on time, backed by responsive service and technical support.
GPD offers both custom and commercial off-the-shelf (COTS) solutions, providing flexibility for customers with varying timelines and technical requirements. While many customers rely on our standard product offerings to meet immediate needs, we specialize in developing tailored solutions that meet unique application requirements. Our agile engineering team works closely with customers from concept through production, often delivering prototypes within just a few weeks. This ability to rapidly design, iterate, and scale sets us apart in industries where precision and speed are critical.
Our vertically integrated manufacturing process ensures quality and consistency at every stage. From in-house wafer design and testing to package assembly and final inspection, all key processes are managed within our facility. Our capabilities include advanced photodiode design, chip-fabrication support, and a wide range of packaging options, including TO cans, chip-on-submount assemblies, and leadless chip carriers. With on-site CNC machining and 3D printing resources, we can quickly adapt to new design requirements and produce custom components with tight tolerances.
To maintain the highest standards of performance and reliability, GPD operates Class 1,000 and 10,000 cleanroom environments and offers hermetic sealing, automated assembly, and comprehensive testing services. Our quality system is compliant with MIL-I-45208, and our products are tested to rigorous industry standards, including Telcordia (TA-NWT-000983) and MIL-STD-883 methods, as well as customer-specific requirements. GPD Optoelectronics is ISO 9001:2015 certified, underscoring our commitment to quality management and continuous improvement.
For over five decades, GPD Optoelectronics has been a trusted partner to customers across industries, including aerospace, defense, medical, and industrial sensing. From initial design through the full product lifecycle, we are dedicated to helping our customers achieve success with reliable, high-performance photonic solutions.
