Abstract

A fiber-optic single-sideband frequency shifter has been demonstrated that uses a surface acoustic wave incident upon an optical fiber at an angle to produce phase-matched polarization coupling. Coupling efficiencies as high as 95% at 4.4 MHz have been obtained using 25 W of input power (electrical). A tuning range of 290 kHz was achieved. Sideband suppressions of 40 dB and carrier suppressions as high as 25 dB have been observed.
