Pushing the room temperature continous-wave operation limit of GaSb-based interband cascade lasers beyond 6 $\mu$m

Josephine Nauschütz, Hedwig Knötig, Robert Weih +4

We present GaSb-based interband cascade lasers emitting at a center wavelength of 6.12 $\mu$m at 20${}^{\circ }$C in continuous-wave operation up to a maximum operating temperature of 40$…
