LED39

TECHNICAL DATA

Mid-Infrared Light Emitting Diode

Light Emitting Diodes with central wavelength 3.90 µm series are based on heterostructures grown

on InAs substrates by MOCVD. InAsSb is used in the active layer. Wide band gap solid solutions

InAsSbP with P content 50% are used for good electron confinement.

LED39 has a stable ouput power and a lifetime more then 80000 hours.
