We have proposed and fabricated an arrayed-waveguide grating (AWG) with an integrated lens system that is designed to obtain a flat output wavefront. A spatial filter or spatial light modulator could be integrated easily at the output facet of the waveguide. A patterned mirror was attached to the AWG, and doubling of the pulse repetition rate was successfully demonstrated.
