Abstract :
Thermal impedance of epi-up and epi-down interband cascade lasers is reported. Two-dimensional heat diffusion model to simulate the temperature distribution in a 6 cascades ICL mounted epi-up or epi-down on an AIN submount is discussed. Lasers are etched through the active region, and they are gold electroplated to a thickness of about 5 μm on the epi-side. Thermal coefficient of 2 W/m-K for the InAs/AISb superlattice upper and lower cladding layers are analysed.
