【Abstract】 The chaotic dynamics of the photoelectron feedback and of the photoelectron injected SCH quantum well lasers are analyzed;the photoelectron feedback and the photoelectron injected SCH quantum well lasers are used to be transmitter and receiver respectively;the synchronization and synchronization communication of the above two systems are researched by the means of theoretic analysis and numerical simulation.Both the theoretic analysis and numerical simulation show that it can communicate commendably by using the synchronization of the above two laser systems.The problem of other systems’ can only delivering small signal in chaotic communication is overcome with the application to this laser’s scheme.更多还原
