We present an integrated multi-wavelength ringlaser. The ringlaser contains two identical 4-channel phased-array (de)multiplexers with 4 integrated SOAs in 4 waveguides connecting them, 1 for each wavelength channel (400 GHz spacing). Another SOA is placed in the multiplexed part of the ring. Light is coupled out by waveguides that are positioned in the second order of the multiplexers. The phased arrays were fabricated using a double-etch technique, enabling a total size of only 1.5??3 mm2. Facet reflections are minimized by using modefilters and angled facets. Threshold-currents of 70 mA and a side mode suppression ratio of 30 dB were measured.
