【 摘 要 】

We find theoretically that the optical modulation instability can spontaneously happen in the noninstantaneous defocusing medium when there is a coherent feedback. it requires both above-threshold gain and phase matching for the instability to happen. very similar to the oscillation condition of a laser. The theoretical result is in good agreement with our experimental observation. (C) 2009 Elsevier B.V. All rights reserved.
