germanium photodiode

germanium photodiode: A germanium-based PN- or PIN-junction photodiode. Note 1: Germanium photodiodes are useful for direct detection of optical wavelengths from approximately 1

m to several tens of

m. Note 2: Germanium-based detectors are noisier than silicon-based detectors. Silicon-based detectors are therefore usually preferred for wavelengths shorter than 1

m. [After FAA]
