We propose that quantum well structures are effective for decreasing the nonlinear damping constant, K factor(Γ = Kf^2_r, Γ: damping factor, f_r: relaxation oscillation frequency) in semiconductor lasers. Theoretically calculated results indicate that by using quantum well structures with low threshold gain the K factor can be reduced by about 50% and the frequency limited by the nonlinear damping is a maximum of 50 GHz.
