Abstract

A low-threshold 7.3 μm superlattice-based quantum cascade laser with 3.4 kA/cm² threshold current density at 300 K is grown using gas-source molecular beam epitaxy. >100 mW peak output power is observed for a 20 μm×2 mm stripe with 153 mW/A slope efficiency of 650 mW/A and low sensitivity to temperature changes is evidenced at 210 K high characteristic temperature.
