In this theoretical article we are going to study effect of quantum well width, quantum dot size and mole fraction of Al for nonlinear refractive index and self-focusing effects in a new nanostructure AlGaN/GaN spherical quantum dot. The Schrodinger equation in spherical coordinate system was solved and wave functions, third order susceptibility, nonlinear refractive index and distance of self-focusing obtained. The results show that new nanostructure has interest property for self-focusing phenomenon.
