Specialty Photodiodes
High-Performance Photodiodes & Custom Detector Solutions
GPD Optoelectronics offers specialized photodiodes engineered for advanced optical sensing and measurement. Our portfolio includes low-PDL InGaAs detectors and two-color sensors—each designed for stability, spectral versatility, and seamless integration into fiber-optic and instrumentation systems.
Two-Color Detectors
Two-color detectors integrate stacked photodiodes within a single package, enabling extended spectral coverage and ratio-based measurement. These devices are ideal for applications such as spectrophotometry, remote temperature sensing, and any use case requiring accurate wavelength differentiation.
Low Polarization-Dependent Loss InGaAs Photodiodes
Low-PDL InGaAs photodiodes deliver reliable, polarization-insensitive detection across near-infrared wavelengths. By reducing polarization-dependent loss, they ensure consistent responsivity in fiber-optic systems, spectroscopy, sensing applications, and precision test and measurement environments.
