FIG. 1.

Illustration of the designed phase shifter. The mode-carrying waveguide is paralleled by a non-mode-carrying nanostring. (a) The nanostring is double-clamped. (b) The nanostring is set to be a cantilever. (c) Mode profile in cross-section. (d) The effective refractive index of the waveguide and the optical force in dependence of the gap.

(a) Deflection curve of the phase-shifter in the case of double-clamped beam (). (b) The effective refractive index along the waveguide in the case of double-clamped beam (). The light-blue shaded area corresponds to the delta optical length in this situation. (c) Deflection curve of the phase-shifter in the case of cantilever (). (d) The effective refractive index along the waveguide in the case of cantilever (). The light-blue shaded area corresponds to the delta optical length in this situation.

(a) Dependence of phase shift to the launched power under the two different boundary conditions (while nanostring’s length is fixed to ). (b) Dependence of phase shift to the nanostring’s length under the two different boundary conditions (while launched power is fixed to 0.64 mW). (c) Dependence of phase shift to the launched power and nanostring’s length in the case of double-clamped beam. (d) Dependence of phase shift to the launched power and nanostring’s length in the case of cantilever.
