Anticipated or retarded synchronization of a mutually coupled nonlinear system is experimentally studied through a mutually coupled semiconductor laser system subject to optoelectronic feedback. These two types of synchronization are found to arise from a predictable relation between feedback/coupling delay times under particular feedback/coupling strength combinations. A comparison between the experimental results and the theoretical predictions is completed. The experimental results mostly agree with theoretical predictions. System limitations are also discussed.
