LEDs for 2800-5000 nm spectral range are fabricated from narrow band-gap InAsSb/InAsSbP-based heterostructures lattice-matched to InAs 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.
