Detecting Optical Communication Signals with Precision
Many optical communication systems operate in the near-infrared (NIR) and short-wave infrared (SWIR) ranges, where transmission efficiency and signal integrity are strongest. Detecting these signals reliably requires photodiodes that combine high sensitivity, low noise, and fast response times.
InGaAs photodiodes and germanium photodiodes from GPD Optoelectronics are designed to operate across the 800–1650 nm spectral range, supporting systems where accurate signal detection is critical.
Engineers use our detectors in applications such as:
- Optical communication receivers
- Free-space optical (FSO) communication systems
- Laser monitoring and sensing platforms
In high-performance optical systems, detector performance directly impacts signal quality and overall system reliability.
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
