Summary:
We demonstrated experimentally the synchronization between two semiconductor lasers by the injection of common amplified spontaneous emission (ASE) light, emitted from a super luminescent diode. The synchronization was realized in the both cases of the semiconductor lasers with and without optical feedback. Note that the lasers can behave chaotically with optical feedback. The quality of the synchronization, measured by the cross-correlation coefficients of the two laser outputs, can be improved by increasing the injected ASE light. In addition, we show the condition of the optical spectra to achieve good synchronization.
