A dual grating reflector is a scheme for wavelength stabilization of laser diodes. The fabrication of a dual grating reflector involves the fabrication of a grating coupler on the p-side of a laser diode and a feedback grating on the n-side of the same device. The basic theory of the dual grating reflector is presented, along with the methods used to determine the required tolerances for near optimum performance. The fabrication processes used to obtain the required tolerances needed for a dual grating reflector are presented.
