How to Select the Right Photodetector
Photodetectors sit at the heart of an enormous range of modern systems: fiber optic communications networks, LiDAR sensors in autonomous vehicles, gas analyzers, medical imaging equipment, and precision scientific instruments.
Despite this diversity of applications, the selection process follows a consistent logic that is grounded in four fundamental questions about your system and a working knowledge of the core trade-offs:
- What wavelength range must we detect?
- How quickly must the system respond?
- How strong is the optical signal?
- Do we need to measure the position or movement of the beam?
The answers help the engineers at GPD Optoelectronics narrow the choice between standard and extended InGaAs, high-speed InGaAs, germanium, avalanche photodiodes, quadrant detectors and position-sensing devices.
GPD developed a new Photodetector Selector guide to provide engineers a practical starting point for matching detector technology to real application requirements, before spending time comparing individual devices.
In addition, GPD also recently launched a “Photodetector Buyer’s Guide” that goes deeper into specs and system-level considerations. Whether you are designing a new system from scratch or troubleshooting unexpected noise in an existing one, understanding how these variables interact is the fastest path to a confident, defensible choice of components.
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 sensing photodiodes
- Specialty photodiodes
- Packaging Options
- Multi-Cell Photoreceiver (MCPR) Development Kits
