Summary:
We experimentally investigate bandwidth enhancement of chaos in a semiconductor laser (drive laser) subject to optical injection from another chaotic semiconductor laser (injection laser). The bandwidth enhancement is achieved when the optical wavelength of the drive laser is mismatched to that of the injection laser out of the injection locking range. A bandwidth-enhanced chaotic signal of the drive laser is injected into a third semiconductor laser (response laser). Synchronization of bandwidth-enhanced chaos is observed between the drive and response lasers when the optical wavelengths of the drive and response lasers are matched to each other due to the injection locking effect. High quality of synchronization is achieved in the injection locking range.
