<p>Device which in one aspect effects a continuous realignment of the optical fiber (11) 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 (12) to a piezoelectric crystal (13) which expands and contracts in response to electrical pulses supplied to electrodes (15, 16) on the crystal. Clamping and releasing the ends (14, 12) of the crystal by magnetic (18, 19) or electrostatic forces result in movement of the fiber in incremental steps to its aligned position.</p> |
