Paper Abstract

A fiber-optic frequency shifter utilizing torsional acoustic waves to produce a travelling perturbation which couples the polarization modes of a linearly birefringent optical fiber is demonstrated. The shift in optical frequency was 3.195 MHz and an optical coupling efficiency of 6% was obtained with 780 mW of electrical power.
