Abstract
An integral waveguide is formed in the epitaxial layers as a continuation of a diode laser. The waveguide runs away from the laser active region. Light is coupled out of the laser and its integral waveguide into a dielectric waveguide which runs parallel and adjacent to the integral waveguide. Processing to form the temperature-stabilized Bragg grating, therefore, need not be performed on the laser substrate directly adjacent to the active area, but can be done some distance away to avoid damage to the laser's active area.
