A multi-transverse-optical-mode heterojunction diode laser characterized by wavelength control of its output. The wavelength control or the control of multi-transverse-optical-modes may be achieved by, for example, selectively etching a layer to partially remove it and possibly followed by epitaxial regrowth, or by selectively converting a layer to an insulating material of a different refractive index, or by selectively modifying the optical properties of a layer by ion implantation, or by selectively modifying the optical properties of a layer by impurity-induced vacancy disordering.
