In order to see the effect the change of the quantum well structure on the characteristic temperatures  different structures were attempted. For the 808 nm structure  we tried different barrier thicknesses. For the 810 nm structure  different cavity lengths were attempted. And we studied the 940 nm and 980 nm also. In this paper  the widths of these devices were all 100 m. Characteristic temperatures of these devices were calculated. The appropriate structure was available for different application. 2008 SPIE.
