摘要: Multi-wavelength light sources by narrow-band spectral filtering of multi-mode lasers have been studied for wavelength division multiplexing (WDM) applications. Long-wavelength Fabry-Perot (FP) semiconductor provide many modes, whose mode spacing can be fixed with precise frequency using a locking technique. However, increased intensity noise has observed in the multi-modes generated mode-locked lasers. This is known as partition noise. The appears an extreme increase relative (RIN) spectrum low regions. limits transmission applications because degradation signal to ratio (SNR). In paper, we demonstrate reduction optical amplifier (SOA). 16-dB SNR recovery reported FP
