Paper Abstract

A frequency shifter has been constructed which uses travelling acoustic flexure waves induced on a single birefringent optical fibre to produce coupling between the two orthogonal polarisation states. A scheme for determination of the axis orientation is described and an experimental technique for the measurement of the dispersion relation of the flexure waves is presented. Equations are given which enable the approximate value of the mode coupling constant κ to be found.
