Phys. Rev. A 81, 033802 (2010) [7 pages]Optical injection in semiconductor ring lasersReceived 8 December 2009; published 4 March 2010 We theoretically investigate optical injection in semiconductor ring lasers and disclose several dynamical regimes. Through numerical simulations and bifurcation continuation, two separate parameter regions in which two different injection-locked solutions coexist are revealed, in addition to a region in which a frequency-locked limit cycle coexists with an injection-locked solution. Finally, an antiphase chaotic regime without the involvement of any carrier dynamics is revealed. Parallels are drawn with the onset of chaos in the periodically forced Duffing oscillator. © 2010 The American Physical Society URL:
