IBSG's Photodiodes General

General

Photodiodes that IBSG manufactures are based on heterostructures with wide band-gap window. PD24 and PD25 models are based on GaInAsSb/GaAlAsSb structure, PD36 is based on InAs/InAsSbP structure. Fast response time makes them suitable for detection of high-frequency modulated IR laser radiation.The device is mounted on the TO-18 package or TO-5 package with thermocooler inside and can be equipped with the parabolic reflector.
Three types photodiodes - PD24, PD25 and PD36 can operate in photo-voltaic regime or at reverse bias. Here are presented curves of detectivity vs wavelength at room temperature. With increasing temperature (using thermo-electric cooler) detectivity increases and cut-off wavelength shifts to shorter wavelengths.
