Abstract:
1. A polarization controller comprising: a phase retarder having a rotation about an {1,0,0} axis, said phase retarder coupled to a waveguide structure receiving an optical signal; and at least two nanoelectromechanical dielectric perturbers that produce ±45° birefringent axes by placing said at least two nanoelectromechanical dielectric perturbers at selective positions around said waveguide structure to produce dynamic change in the effective index in one of the modes existent in an extraordinary axial direction by the sliding motion of said at least two nanoelectromechanical dielectric perturbers using a suspended structure double-anchored on both sides of said waveguide with at least one comb-drive actuation mechanism.
