In this paper, we present a theoretical study on the properties of wavelength shift due to quantum well (QW) intermixing in the partly gain-coupled distributed feedback (DFB) lasers. A maximum possible wavelength red-shift of 9.2 nm is predicted if using a proper DFB grating, whose period is smaller
