【Abstract】 The dynamic characteristic of semiconductor laser with external-cavity optical feedback is studied. By simulation,the results show: for small optical feedback, the system is stable;with increasing feedback amount, the system induces irregular oscillation through periodic oscillation. But, with increasing feedback amount successively, the output of the system is not periodic oscillation but becomes irregular impulse.更多还原
