A monolithic laser diode and monitor photodetector is disclosed wherein the photodetector is placed at a tilt angle chi , within a predetermined range of tilt angles, with respect to the laser diode back facet. The predetermined range of tilt angles is selected according to the thickness and refractive index of the dielectric coating so as to reduce the susceptibility of the photodetector performance to variations in the dielectric coating deposited simultaneously on the output facet of the laser diode and the light collection surface of the photodetector and to significantly reduce the amount of the optical power reflected from the light collection surface of the photodetector onto the laser diode back facet.
