Abstract

Recently, we proposed a spectrum-sliced fiber-amplifier light source for multichannel WDM systems.¹ The high-power ASE from an EDFA, which is already in the single-mode fiber, could be efficiently divided into many channels by using integrated-optic WDM demultiplexers.² Thus, this spectrum-sliced ASE could be used as a light source for WDM systems in place of several wavelength-selected DFB lasers. To demonstrate the principle, we showed that the spectrum-sliced ASE source could be used for transmission of 1.7-Gbit/s data. The application of these light sources is not limited to local-loop networks. In this paper we show that when the spectrum-sliced fiber-amplifier light source is used, it is possible to launch high optical power (>22 dBm) into the single-mode optical fiber without the limitation imposed by stimulated Brillouin scattering (SBS)
