Analysis of properties of the multiwavelength source with an acousto-optic frequency shifter

The article presents the simulation of a ring configuration system which generates a multiwavelength signal (comb of carriers), together with its basic components: a single laser, an optical splitter, an acousto-optic frequency shifter (AOFS) and an optical amplifier (OA). Optical filters are used to shape the spectrum of the generated multiwavelength signal in the system. Combs with a number of carriers ranging from 20 to 60 were accomplished, with an optical carrier to noise ratio (OCNR) higher than 30dB.
