3 pages, 5 figures., A modified ring laser geometry is presented to promote stable unidirectional lasing. The effects of directional coupling and facet reflectivities are investigated with respect to quantum efficiency, directionality, and side-mode suppression ratio of the lasing spectra. Simulation and experimental results are presented showing single mode (>20 dB side-mode suppression ratio), unidirectional lasing on an InP based multiple quantum well material., We acknowledge financial support from the EU Grant No. FP6-2005-IST-5 through project IOLOS (034743) and partial support of S. Balle through project TEC2006-13887-C05-03, and of J. Danckaert and G. Verschaffelt from IAP VI/10 and FWO.
