Low Polarization-Dependent Loss InGaAs Photodiodes
Polarization-Sensitive Applications
Low-PDL InGaAs photodiodes are engineered for stable optical detection with minimal sensitivity to variations in light polarization.
By reducing polarization-dependent loss, they maintain consistent responsivity across changing polarization states, enhancing measurement accuracy in systems where polarization control is limited.
Built on InGaAs technology, these photodiodes operate across near-infrared wavelengths widely used in fiber-optic, sensing, and instrumentation applications. Their low polarization dependence minimizes signal fluctuations in fiber-coupled systems, interferometric setups, and other precision optical measurements.
These devices are commonly used in optical communications, laser power monitoring, spectroscopy, and test-and-measurement environments. A range of packaging and configuration options enables straightforward integration into systems requiring stable, polarization-independent performance.
