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.
