Optical chaos communication encounters difficulty in high-speed transmission due to the challenge of realizing wideband chaos synchronization.Here,we experimentally demonstrate a wideband chaos synchronization using discrete-mode semiconductor lasers (DMLs) in a simple master-slave open-loop configuration. Wideband chaos with a bandwidth of 30GHz can be generated in the master DML only subject to an external mirror feedback, which greatly reduces the configuration complicacy. The reason for the wideband chaos generation is that main-mode and side-mode light emissions coexist in the DML, and the optical beating between them stimulates high-frequency oscil-lation. After injecting the wideband chaos into a solitary DML, the master-slave wideband synchronization with a synchronization coefficient of 0.88 can be readily achieved. Parameter range of frequency detuning and injection strength for yielding the wideband synchronization is ascertained. It is believed that this work paves the way of wideband chaos synchronization using a simple configuration and underlies the high-speed optical chaos communication.
