Photodiodes for 1.5-3.8 µm spectral range
The PD36 series of photodiodes for 1.5-3.8 µm spectral range are produced on the base of the InAs/InAsSbP heterostructure. The main advantage of this heterostructure is high crystalline quality of epitaxial layers with low density of dislocations (104 cm–2). The doping level of the active GaInAsSb layer (up to 1015-1016 cm–3) makes it possible to reach low capacity and high response speed for PDs. Photodiodes are manufactured with the sensitive area diameters from 100 µm to 2 mm.
- Main applications:
- - Diode-Lasers spectroscopy;
- - Environmental monitoring;
- - Medicine;
- - Remote non-contact temperature measurements;
- - Detection of the burning or explosion products.
