Abstract
The state of polarization of light propagating in a polarization-preserving fiber may be varied via the acousto-optic effect by introducing high-frequency acoustic waves into the core region of the fiber. This effect may provide active polarization control for applications in interferometry, switching, and amplitude modulation. This paper describes a method for inducing polarization coupling within an optical fiber by coupling bulk shear acoustic waves through the flat surface of an elliptical-core D-fiber. The theory of device operation is developed, and a device model is characterized. The effect is experimentally verified with a first-generation device achieving approximately 7% amplitude coupling efficiency at 2 W input electrical power at a frequency of 22.7 MHz.
