This work presents a frequency multiplier generated by a fiber optic Sagnac interferometer based on cascade integrated-optic phase modulators. The effective Vπ of this interferometer can be reduced to Vπ/2N, where N is the number of phase modulators. The generated frequencies depend on the applied modulation amplitude and the number of integrated-optic phase modulators. The output frequency can be multiplied by simultaneously using two integrated-optic phase modulators employed with π rad out of phase of each other. Experimental results indicate that a stable frequency of 1.008 GHz, i.e., 24 times higher than the modulation frequency, can be easily achieved by applying a low modulation frequency to the optical interferometric system.
