TECHNICAL DATA
Mid-Infrared Light Emitting Diode
Light Emitting Diodes with central wavelength 1.95 µm series are based on heterostructures grown
on GaSb substrates by LPE. Solid solutions GaInAsSb are used in the active layer. Wide band gap
solid solutions AlGaAsSb with Al content 64% are used for good electron confinement.
LED19 has a stable ouput power and a lifetime more then 80000 hours.

LED19
We recommend to use Quasi Continuous Wave (qCW) mode with duty cycle 50% or 25% to obtain
maximum average optical power and short Pulse mode to obtain maximum peak power.
Hard CW (continues wave) mode is NOT recommended.
