    Abstract

    Dual wavelength high-frequency chaos based on nonlinear effects is generated in an erbium-doped fibre ring laser, where tunable filters (TFs) are used to select the wavelength. A receiving fibre laser with an open-loop structure is constructed with identical parameters as the transmitting fibre laser. By tuning the TFs and the fibre delay line in the receiving fibre laser, chaos synchronization has been observed at anyone the two wavelengths after the chaos is transmitted over 1 km. It is of far reaching importance to construct the high capacity chaos communication system. ©2005 Chinese Physical Society and IOP Publishing Ltd. ©2005 Chinese Physical Society and IOP Publishing Ltd.
