Theoretical and Experimental Study on Flat Optical Comb Generation Based on Re-Circulating Frequency Shifter

Abstract:

A complete analysis of flat and stable optical comb generation based on the re-circulating frequency shifter has been analyzed and demonstrated in this paper. We find out the influence to the flatness of optical comb owing to amplifier relative intensity noise and modulator relative factors imperfect, such as input RF signals amplitude and phase deviation and modulator defect owing to manufacture for the first time. Moreover, to verify the theoretical analysis, a 16 comb lines and spacing 12.5 GHz RFS generation system have also been carried out, and the results are in good agreement with the theoretical analysis results.
