Abstract :
A ten-stage interband cascade laser with 13 mum-wide, 4 mm-long ridge waveguide and Au electroplating for improved epitaxial-side-up heatsinking operates CW to a temperature of 269 K, where the emission wavelength is 4.05 mum. Maximum CW output powers are 130 mW at 78 K, 58 mW at 200 K, and 9 mW at 260 K, and the threshold current density at T=260 K is 660 A/cm2
