A novel fiber phase-shifter is proposed. It is based on the birefringence effect induced when a polarization-maintaining optical fiber is deformed periodically. The relative phase delay between two fiber modes is altered by fiber axis perturbations to produce a light beam deflection of the far-field pattern by 20 degrees.
