We demonstrate for the first time to our knowledge a new oscillator based upon SAW device and optical device. The unique characteristic of the hybrid acousto-electro-optic oscillator is that its overall oscillator loop can be longer than several hundreds kilometers, contrast remarkably to its pure electronics oscillator counterpart for only several millimeters or several centimeter long because that the loss in optical fiber is much less than that in electric cable.
