Backward-pumping WDM fiber laser sources using gain fibers of various lengths as self-equalizers

摘要

In order to increase the information capacity in wavelength division multiplexing (WUM) lightwave transmission, the realization of multi-wavelength laser sources with stable, narrow linewidth and equal output power in the 1.55-μm band have been extensively developed recently [1-2]. With the characteristics of compact, low cost and low temperature coefficient, WDM fiber laser sources are promising candidates for lightwave communications [3]. In this paper, we propose and simulate a novel configuration of power-equalized WDM fiber laser sources. The simulation is based on the spectral model of optical amplifier [4]. An 11-channel WDM laser sources with wavelengths λ{sub}S ranging from 1530- to 1560 nm of 3.0 nm channel spacing is studied. The parameters used here are similar to that in ref..
