Claim 0:
1. An optical element for transmitting a light beam comprising:
a waveguide configured to propagate the light beam from an input end to an output end, said waveguide having an optical property that can be modified by deformation of said waveguide; and
a phase-shifter affixed to said waveguide, said phase-shifter configured and operable in response to a control signal to mechanically deform or deflect said waveguide in response to a control signal sufficient to induce a phase shift in the light beam propagated therethrough,
wherein:
said waveguide is mounted on a substrate,
said phase-shifter includes a first phase-shifter component affixed between said waveguide and said substrate and a second phase-shifter component affixed to said waveguide on a surface of said waveguide opposite said substrate, and
said substrate is configured to define an air gap between said substrate and said second phase-shifter component.
