We propose the generation of a multiwavelength spectrum based on Rayleigh backscattering. An erbium-doped fiber amplifier (EDFA) and a Lyot filter act as gain medium and comb filter, respectively. A high number of stable lasing lines is achieved at 51 channels with a 21 dB extinction ratio using 18...
