ABSTRACT:
Disclosed is a device which in one aspect effects a continuous realignment of the optical fiber in transmitters, receivers, or transceivers after the lightwave package is assembled and in use, and in another aspect provides movement of optical fibers or other small elements for general applications. In one embodiment, the fiber is mechanically coupled to a piezoelectric crystal which expands and contracts in response to electrical pulses supplied to electrodes on the crystal. Clamping and releasing the ends of the crystal by magnetic or electrostatic forces result in movement of the fiber in incremental steps to its aligned position.
