Paper Abstract

We propose a novel 10-GHz-order frequency shifter using Bragg diffraction in electro-optic traveling phase grating with slant-stripe-typed periodic domain inversion. The principle of frequency shift is same as acousto-optic frequency shifter. However, no electro-optic frequency shifter in 10-GHz-order or less using Bragg diffraction has been developed so far because the wavelength of electromagnetic wave is too long to cause Bragg diffraction. Our new frequency shifter has the feature that spatial period of the phase grating does not depend on not the wavelength of modulating microwave but the period of domain inversion. Therefore, the period of the phase grating small enough to cause Bragg diffraction is possible in the frequency range of over 10 GHz by using our new device. Simulation results from Beam Propagation Method indicates that only the first-order diffraction occurs at the output end of this device, and the optical frequency is shifted by modulating microwave frequency.
