Paper Abstract

We demonstrate a single-sideband in-fiber frequency shifter using acousto-optic polarization mode coupling. Using 200 mW power to a bulk shear-wave acoustic transducer bonded to a polarization-preserving D-fiber, we have observed power coupling from an optical carrier to an upper sideband, shifted by the 17.5 MHz acoustic frequency. The suppression of the lower sideband, relative to the upper sideband level is at least 10 dB, with the actual sideband level below the noise level of the experiment. This frequency shifting property may be used for the development of in-fiber Bragg cells with improvement of the weak 0.16% observed power coupling efficiency in this work.
