Precise wavelength control in a multi-wavelength laser array is an important issue concerning practical applications. The wavelength is dictated by material and structural parameters. By controlling the waveguide dimension and waveguide orientation the lasing wavelength can be controlled. This can be done by varying the ridge width and ridge angle with respect to the DFB gratings. In this paper, a three-dimensional DFB laser model is presented. This is used to study the extent of wavelength tunability in DFB laser arrays.
