Abstract

We review recent NRL progress in the development of interband cascade lasers for the 3–4 μm spectral range. The maximum cw operating temperature has reached 269 K, and the pulsed threshold current density at room temperature is as low as 790 A/cm2. The internal loss in a broad-area laser (λ = 3.5–3.9 μm) varies from 11 cm−1 at 78 K to 28 cm−1 at 275 K, and most of the increase in threshold with temperature (T 0 ≈ 40 K) is due to a shorter non-radiative lifetime. We also discuss a distributed-feedback laser that demonstrated stable single-mode operation at all temperatures between 78 and 160 K, with a side-mode suppression ratio ≥25 dB.
