Abstract :
In this demonstration, a stable and flattened quadruple-wavelength laser system is proposed and experimentally investigated by using four-wave mixing (FWM) generated by an external-injection Fabry-Perot laser diode (FP-LD) and a stimulated-Brillouin-scattering (SBS)-assisted filter. In the measurement, the power difference (AP) of lasing quadruple-wavelength can be enhanced within 2.0 dB by SBS-assisted filtering after 22 km single-mode fiber (SMF) propagation. In addition, we can vary the two injected wavelengths for tuning the quadruple-wavelength arbitrarily in C-band operation. Besides, the output stability of the proposed laser scheme has been also studied and analyzed.
