Abstract
An optical element for transmitting a light beam includes a waveguide configured to transmit the light beam from an input end to an output end and having an optical property that can be modified by deformation of the waveguide. A phase-shifter is affixed to the waveguide and is operable in response to a control signal to mechanically deform the waveguide sufficient to induce a phase shift in the light beam transmitted therethrough. The phase-shifter can include a PZT layer.
