LEDs for 1.6-2.4 µm spectral range are fabricated from narrow band-gap GaInAsSb/AlGaAsSb-based heterostructures lattice matched to GaSb substrate.
Maximum operating current at quasi-CW mode is 250 mA;
Maximum operating current at pulse mode is 2 000 mA;
Switching time is 30-50 ns;
Operating temperature range is -200…+50 °C.
