An experimental demonstration of the chaotic synchronization between two injection-locked semiconductor lasers is reported in this paper. Optical injection on the semiconductor laser not only generates optical chaotic output, but also broadens the bandwidth up to two fold of the laser intrinsic bandwidth. Since the chaotic synchronization based on this system is very sensitive to optical phase, the synchronization quality subject to both phase match and phase mismatch is measured in both time and frequency domains. The synchronization quality of each case is quantitatively expressed by the correlation coefficient.
