Fiber-Coupled InGaAs PINs and APDs
GPD Optoelectronics provides fiber-coupled InGaAs PINs and avalanche photodiodes (APDs).
These components are engineered for low-capacitance and high-speed detection in fiber-optic systems requiring precise signal integrity. GPD products are optimized for high-bandwidth applications in telecom, LiDAR, spectroscopy, and free-space optics.
Key specifications include:
- Single-mode and multi-mode fiber configurations
- Customizable active areas for application-specific optimization
- Precision optical alignment and rugged mechanical packaging
About GPD Optoelectronics
Founded in 1973, GPD Optoelectronics began by making high-quality germanium transistors, but since the early 1980s the company manufactures both germanium and indium gallium arsenide photodiodes and multi-element photodetectors. In addition to offering a variety of off-the-shelf products, GPD specializes in providing customized parts that are uniquely tailored to customer applications. GPD has the agility to design and deliver prototypes of custom products often within just a few weeks.
GPD’s products include:
- Photodiodes
- Position sensors
- Avalanche photodiodes – InGaAs APDs
- Specialty products
