Paper Abstract

Under suitable filtered optical feedback, a weak-resonant cavity Fabray-Perot laser diode (WRC-FPLD) is rendered into chaotic state, and the central wavelength of chaotic output can be tuned through varying the central wavelength of filter. The output chaotic signal with wavelength-tunability is unidirectionally injected into another WRC-FPLD and drives it into chaotic state, and then wavelength-tunability chaos synchronization can be realized. The experimental results demonstrate that, under suitable injection strength and frequency detuning, chaos synchronization between two unidirectionally coupled WRC-FPLDs with maximal correlation coefficient about 0.900 can be achieved under different wavelengths.
