A monolithically integrated diode laser with waveguide devices has been described theoretically and experimentally. The lateral-electrode ridge-guided Fabry-Perot or DFB laser is coupled by the evanescent field to a strip loaded single-mode waveguide. The waveguide cladding consists of two layers: the upper layer is n-doped for a ground contact of the laser section, and the lower layer is nondoped to achieve low loss propagation in the waveguide. This device will be useful as a built-in component for various optical measurement equipments.
