This study demonstrates signal-to-noise ratio improvement of a 300-GHz carrier via multiple comb-mode optical-beat interference in an electro-optic modulation comb. The SNR was improved by simultaneously inputting multiple comb-spectrum into a uni-traveling-carrier photodiode and constructively adding the 300 GHz optical beat signals generated from each spectral pair. Increasing the number of input combs resulted in a maximum improvement of approximately 4 dB in the power of the intermediate frequency signal, demonstrating the effectiveness of this method.
