We present a novel multi-wavelength laser based on on-chip filtered optical feedback. The monolithically integrated device consists of four Fabry-Perot (FP) lasers that are wavelength-locked by an on-chip filtered-feedback section. The FP mirrors are formed by two on-chip multimode interference (MMI) reflectors, and the feedback section contains four phase shifters and a reflective arrayed waveguide grating to provide the filtered-feedback. By controlling the current injection to the lasers, single mode operation in each channel can be achieved. In this paper the design, fabrication and the first measurement are presented.
