Abstract: We report on directional mode switching in semiconductor ring lasers through optical injection co-propagating with the lasing mode. The understanding of this novel feature in ring lasers is based on the particular structure of a two-dimensional asymptotic phase space. Our theoretical results are verified numerically and experimentally. © 2008 Optical Society of America OCIS codes: (140.3560) Lasers, ring; (140.5960) Semiconductor lasers; (190.1450) Bistability
