✦ Synopsis
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.
