Abstract
We propose and demonstrate an electro-optic (EO) multiplication of a frequency shift using 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 crystal. Frequency shifting of with an efficiency of 60% is demonstrated using a modulation signal.
