We study the electronic and optical properties of GaAs quantum dot embedded in Ga1-yAlyAs matrix. Using the effective mass approximation with the finite confinement potential the intraband energy levels and the wavefunctions are obtained. The linear and third order nonlinear optical properties, photoabsorption coefficient, refractive index change and susceptibility are studied for different dot radius in the terahertz region.
