A cost effective method of generating multi-wavelength based on the cascaded four wave mixing effect is experimentally demonstrated. The proposed scheme is free from external tunable laser sources and pump modulators, resulting from the use of a broadened linewidth tunable dual wavelength erbium-doped fiber laser as intracavity pump. In this configuration,… (More)
In this paper, the influence of the rotating polarization angle of optical feedback (OF) on the chaotic dynamic behavior of vertical-cavity surface-emitting lasers (VCSELs) is studied numerically. Parallel-polarization optical feedback (PPOF) is considered in this investigation. A numerical model using Simulink is implemented for the polarization resolved… (More)

We propose and demonstrate improvement of optical signal-to-noise ratio of a high-power pump by saturated stimulated Brillouin amplification of a backward seed in a fiber. A 27-dB improvement was obtained for a 1-W pump.
