Abstract: A novel semiconductor laser formed by monolithically integrating an array of active stripes with a passive planar waveguide bearing an etched-in diffraction grating is reported. Laser emission occurs from different stripes at different, precisely predetermined, wavelengths. It is expected that this laser will find widespread application in wavelength division multiplexed networks.
