A 1 x 2 precise electro-optic switch was demonstrated in a periodically poled lithium niobate crystal. In the experiment, the optical signal was shifted to different channels by adjusting external applied electric fields. The bandwidth of the working wavelength for the switch is nearly 2 nm, which makes this device has large tolerance to the drift of the working wavelength in the practical applications. Theoretical discussion about 1 x 2 precise electro-optic switch based on this structure is also presented.
