Abstract:
1. A wavelength division multiplexing light source for optical networks, comprising: a broadband light source for creating a broadband light including a plurality of incoherent lights having different wavelengths; a plurality of optical modules each including a first area for amplifying the incoherent lights and optical signals and a second area for creating optical signals having the same wavelengths as the incoherent lights amplified by means of the first area wherein said second areas amplify and modulate the incoherent lights amplified at the first areas, respectively; and a multiplexer/demultiplexer disposed between the broadband light source and the optical modules for demultiplexing the broadband light into the incoherent lights so that the demultiplexed incoherent lights are outputted to the optical modules, respectively, and for multiplexing the plurality of optical signals having different wavelengths received from the optical modules so that the multiplexed optical signals are outputted.
