Paper Abstract

InAs-based interband cascade (IC) lasers with improved optical confinement have achieved high-temperature operation with a threshold current density as low as 333    A / cm 2 at 300 K for emission at 6003 nm. The threshold current density is the lowest ever reported among semiconductor midinfrared lasers at similar wavelengths. These InAs-based IC devices lased in pulsed mode at temperatures up to 357 K near 6.28    μ m . A narrow-ridge device was able to operate in continuous-wave mode at temperatures up to 293 K at 6.01    μ m .
