Abstract
A planar coil of single mode fiber has opposed ends twisted into orthogonal planes to form a non-planar coil 20 exhibiting circular birefringence. The amount of birefringence exhibited is modulated by means of an electromechanical transducer 34 which controls the distance separating two diametrically opposed portions of the coil. Two or more such controllers may be formed in tandem with intervening additional coils 50 providing quarter-wave linear birefringence.
