A ringlaser was realised by monolithic integration of a 4x4 phased array (de)multiplexer with four amplifiers in InP. The phased array was fabricated using a double-etch technique, enabling a total size of the ringlaser of only 1 x 1.5 mm2. Light was coupled out by putting outcoupling guides at the outer phased array-arms. Reflections are minimized by using modefilters and angled facets. Threshold-currents of 70 mA and a side mode suppression ratio of 40dB were measured.
