We propose and demonstrate an electro-optic (EO) multiplication of a frequency shift using 10 GHz order electrical signal. The principle is based on a successive Bragg diffraction from cascaded EO traveling phase gratings in a traveling wave EO phase modulator. We fabricate a shift frequency doubler using simple domain engineering processes in a LiTaO 3 crystal. Frequency shifting of ± 32.5 GHz with an efficiency of 60% is demonstrated using a 16.25 GHz modulation signal.
