摘要: We experimentally demonstrate the use of low-cost Fabry-Perot laser diodes (FP-LDs) injected with spectrum-sliced beams from our proposed, depolarized, high-power, continuous-wave (CW) supercontinuum (SC) for upstream transmission in a wavelength-division-multiplexed (WDM) passive optical network. A ~500-mW CW SC ~130-nm bandwidth is obtained narrowband, amplified spontaneous emission (ASE) seed pumped erbium fiber by nonlinear effects such as modulation instability and stimulated Raman scattering highly fiber. Through measurements relative intensity noise at various wavelengths, it shown that offers same performance ASE. Error-free 25-km six WDM signals generated SC-injected FP-LDs, readily achieved 1.25 Gb/s
