A 1550 nm Photodiode is a near-infrared photodetector engineered for high responsivity and low noise at 1550 nm, a primary wavelength band for fiber-optic networks. It is used in optical receivers, coherent and direct-detection systems, power monitoring, free-space optical links, and measurement instruments requiring accurate detection at 1550 nm. Selection is driven by speed, linearity, and dark current. GPD Optoelectronics manufactures photodiodes for operation around 1550 nm.
Learn where near-infrared photodiodes fly in aerospace systems, which specs deserve a hard look, and why in-house fabrication, military-standard testing, and lot-level traceability matter for missions that must work the first time.
