Distributed feedback operation of optically pumped (Zn,Cd)Se/ZnSe quantum-well lasers has been realized at room temperature. The periodic grating structure was fabricated by short wavelength holographic lithography and dry etching techniques. These results are relevant also in the context of the new blue-green diode lasers, based on this same quantum-well system.
