An all-fiber single-sideband frequency shifter has been demonstrated that uses a traveling acoustic wave incident upon a birefringent fiber at an angle to produce phase-matched polarization coupling. The fiber was helically wound on an aluminum cylinder to form a compact device. Conversion efficiency of 75% at 6 MHz has been obtained using 0.4 W of electrical input power. A 3 dB tuning range of 210 KHz was achieved. Sideband and carrier suppressions of 35 and 20 dB, respectively, have been observed.
